Man, that ending felt rushed. Is it really final? I wanted to see more interactions from them. When that final chapter ended, what I felt was like a break-up without closure. Don't get me wrong. The story is really good at the start, but then the final chapters felt REALLY rushed. That ending really did not do it justice 😔

Never before I hated a MC so much since Echo. Coincidentally, they are both otters. VN is very good tho, remove the otter and it will be perfect.

MY GOD YEA, He is even more horny ball then others mc 😂, but i kinda simpatized with that

Hello again Mr. Air it's me Alex It's been three months since I last time Talk to you I just came to tell you that I am now married to xiao We bought a house in California And we live a happy life I really wish I could invite you to my wedding You would be a special guest Because of what you did to my little brother and I thank you again for that if you remember Now Xiao works in a big software company in order to maintain the house and I help him with the work and I have good news I will adopt a child in the future who is still about six months old I'm going to name him after my little brother Michael That's all and I will wait for your games to play in the future 

🐻Xiao ♥️ Me🐶

AWWWWWWWWWWWWW 

That sounds so nice!!! I would so love to assist to attend the wedding🥰🥰🥰 just that I don't have a visa 😅 but I'll be there in spirit with you guys 🫰🥰🫰🥰🫰🥰

It's okay, my friend, I understand the situation 

I have a question

(When will the next update for your game be)

(+1)

The next thing it was planned is another short story from the Short Horns project 🫰

Sorry, I'm not exactly sure how long could it take😅 because of a couple of very dumb accidents, I went through two surgeries at beginning and end of August, (urethral endoscopy and varicocelectomy, so, my genitalia feels mega fucked up right now and for recovery it's -mandatory- not to be horny for two more weeks 🫠 )

Man, I feel like a soccer player that got a mayor surgery on his legs😮‍💨 I wouldn't have minded surgeries in literally any other part of my body 🥹😭🫠 but well

I'll be able to start digging into all those hornee drawings somewhere soon... 

Wish me luck 😅

Oh my God, I didn't know about this. Are you okay? I hope you weren't in too much pain. I wish you a speedy recovery. I'm sorry I didn't know you had surgery. I wish you a speedy recovery

Also, take a break for about two months. You need it.

If I understand correctly, is this the only ending in the game?

There's one good ending. If you deviate from it, the game will loop from near the ending chapters until you get it right 😘

Hello ari can i ask why i can't download short horns anymore? ╥﹏╥

(+1)

There has been a massive vańn!ng of certain themes 😅 try coming to our discord server for getting links.

(By the way, I have never seen someone of your like choose a Discord banner image under a certain context to be proudly on display. Just though that was rare.)

They are fine in the hotel, 

Would you edit and mark this as spoiler and let a lot of spaces before the message, please? 😅

Oh sorry I didn't know sorry 😓But I'm so glad it ended like this, it's so beautiful and sad, I love it❤️And one more question, when will the next update be?Please, as soon as possible.🙏I can't stop thinking about it for a few days now.

(+1)

It's okay! 

Right now it's cooking another little VN for the Short Horns project! 😅

It's called The memory potion 🥰

I'm not exactly sure how long would it take to update Heat source with some more mini chapters/ a filling chapter, maybe some months 😅

(1 edit) (+1)

Okay, I hope it happens soon. I love this. The characters are so beautiful and everything.I hope there will be another chapter.This is beautiful🙏❤️I've read a lot of novels and I've never cried at a single one, but this one did, it's very well done.Thank you for this.❤️❤️❤️

(+1)

Awwwww this really means a lot to me buddy🥰🥰🥰🥰🥰 

Don't worry, things are still planned to come!

(+1)

OMG this VN is so good! Haha, I like Maёva's lullaby "Тили-тили-бом" 😈🎵🎶. Some jokes made me laugh at night, like MC's wet dream about Xiao.  Also I like the way how each of the relatives raised Xiao. (I enjoyed watching him get bullied 😋) I mean its funny tho and he is like "help me, Im big smart silly bear plush 😣))) 

(+3)

AWWWWWWWWWWWWWWWWWWWW 

WHAT A WAY TO DESCRIBE HIMMMMM 🥰🔥💖🥰🔥💖🥰🔥💖🥰🔥💖🥰🔥💖🥰🔥💖🥰🔥💖🥰🔥💖🥰🔥💖🥰🔥💖

(+1)

I love the story!! but one question: how many love interest routes are there? is there one or more? because there are some characters that look too good to NOT date them! Or is those gonna be like side-stories?

There are no current side stories dating other characters😅 but hey, there's a lot of fan service in the Patreon and subscribe star! 😋 If you feel like supporting, the 15 tier gets you access to all previous and upcoming rewards💦💦💦🙌

(+4)

i don't kinda like the end like this it was like we make relationships for a long episode and then just have cheating scenes that i didn't chose,i might be good if can chose a singular characters to be with, love your game btw ><

(+1)

Arii!! This game you created made me cry at the end because of the saddest moment, the way Angel protected the otter made me realizes how much he loves the otter🥹🥹 would you please update it?? I'll just wait for the new update❤️❤️

(+2)

the update was great as always but I've always wanted to ask will there ever be an option where we don't end up in a poly and can chose a singular characters to be with..?

(+1)

Hello again sir Ari I just finished playing I must say I really enjoyed it and learned a lot of information Even I enjoyed the cooking part. I'm excited for the next update xiao Also a new question: Who is this hidden character? I have never seen it before

(+1)

😭💖😭💖😭💖😭💖💖💖💖of course bro!!!

Hi, was wondering if this was available in any way on iOS, browser or not, since it’s tagged under “Phone Browser” in the filters, but not seeing any way to access it except via download. Thanks!

O yikes I think once we had the browser watch available, but it messed up a lot with the songs, so we deleted it... I'll check that out😅

About the iOS, iphone products don't allow nsfw content in their Appstore, so it can be seen in that device, sorry, you would need a Mac, windows, Linux or android device to play it😅

OTTER!

😙🦦

(+1)

I rate this 9.5/10! The story is great and just freaking loved the whole VN. Also I know that there will be side stories that may or may not be involved with the main characters and more so with the world building itself but is there gonna be a part about what happened after the clash with ____________? I mean, I don't know it feels like it ended abruptly. Flashforward and the bam the end. I can't explain it but that's my thought anyway. On the bright side like I said I love it non the less and I mean the size difference it just lovely as always. 

(+1)

Thanks for the review bro!!!

(-1)

Hello sir Ari My name is ALEX I came to tell you About my brother who had cancer He died two weeks after the surgery Before my brother died he told me about you and the games you made You were the reason for making him happy when he was in a state of depression I just want to thank you for everything you've done You made him happy in his last days of his life I will never forget this and I thank you for everything you have done

Woahhh... I'm very sorry for your loss....  The news make me feel terribly sad, but also, I'm happy that this story could have been a little  ease in the last days of his great battle, bro... May his soul be resting in a beautiful  violet beach with a pleasing warm water .... 🙏💝🕯️ May his soul be happy there, swimming with the playful waves towards a new journey...🕯️🥂🥺💖

My little brother was the last person left of my family Now I'm back in college And I live with my boyfriend This is my last year in college I am about to get married soon after I finish college (I think this is a strange coincidence because my boyfriend name is xiao Also he is a fat man His major in college is computer science) I think my brother wasn't joking when he told me my boyfriend looks like xiao

Aww bro I'm sorry to hear that😔I hope for the best of scenarios🙏🙏🙏
and thanks a lot for your kind words 😽

This keeps getting better & better & I can't wait for more

💪🙌🥂🥰

I really liked this one! The pacing can be a bit odd starting very fast then slowing down to a more casual pace. Then the ending was also pretty abrupt and, in my opinion, left quite a lot of drama within the story unresolved.

Knowing that there are bonus chapters to be added I really hope to see some kind of epilogue or slight time skip to explore some of the emotional rifts still left in the cast. As well as a few plot points that weren't explored. Especially involving the MC, Mar and his parents.

Overall a pretty solid read, with only minor spelling and grammar errors; very impressive for what I'm assuming is a first VN for a solo creator.

SPOILERS FOR THE END BELOW PLEASE READ THE VN FIRST

.

.

.

.

This first point is a personal preference, but I'd love a content warning/skip option for the cheating scenes. I understand as a writing decision to have it move the plot forward and change the character dynamics. It is just I personally find that kind of explicit content uncomfortable. and would like a bit of a heads up before hand.

My second spoiler point reiterates  one of my earlier points; all the drama between  the Angel, Mar, and Damian love triangle feels completely unresolved and unexplored. They just go through a major tragic event together and the game ends with a scene of them cuddling. 

I've grown to really care for and want to see these characters happy, so to see all the tension involving the cast kind of swept under the rug to just time skip to a happy ending was a bit disappointing in my opinion.

Even with my minor criticisms towards the VN I really hope to see more! Definitely one of my top 5 VNs and I hope you can see my criticisms come out of a place of care and joy for the experience. :)

i hope in the future i can bring more quality stories❤️‍🔥Thanks for your feedback, it really means a lot to me that you take time to write all that!🥂🙏❤️‍🔥

So when can other articles be published?I really like your work.Played more than 10 times!I hope to publish other chapters soon.Love you, my brother.😘😚

These next few weeks will be working on a silly mini chapter. It's not gonna be a big thing, but I'll put my heart on it💖 that's what's currently scheduled.

Oh, well, thank you for your reply. I hope that day will come soon.    ☺️

Just need at least two more weeks 🤭
