SYNOPSIS
In the year 5066, Danya and his alien friend Juniper are manning The Ameretat, a humble spaceship that transports goods across the Milky Way.
After a troubled transport gig that left their beloved ship in need of repair and their bank account empty, the team is offered a generous deal they cannot refuse: transporting a beautiful and mysterious alien who calls himself Brahve.
Sometimes at night, Danya hears strange things from Brahve's room. What could he be hiding in there? And how will it affect the connection that's quickly growing between the two men?

The demo is amazing! the art is gorgeous, the characters are beautiful and I'm already so curious about how the story is going to go π That Oatith reveal took me by surprise π
Btw, will Danya and Brahve have a somewhat equal number of scenes where they top/bottom in the full version?
The demo was amazing! Just wanna clarify if i can still get the full nsfw android version if I back the project on KS?
Awesome! Very glad you enjoyed the demo. And yes! Supporting us on Kickstarter gets you a full NSFW game on Android via an itch.io key.
I LOVE THE ART??!!? IT'S SO GOOD. *slides credit card across table* THE DEMO WAS FANTASTIC THANK YOU
Swweeet! That is amazing news <3 Thank you for your support! :D
Played the NSFW demo and damn am I left wanting more!!! This is looking amazing and I do hope you meet your goal!! The art style, the characters...just perfect!
Thank you so much for the kind words! <3 We're very happy to hear that you enjoyed the demo! Fingers crossed for a successful Kickstarter :D
πππ

I really REALLY love this game the art style super good and the story so far is really good too and don't get me start on the music <3 I can't wait to have the full game in hand <3<3<3 keep up the awesome work guys :D!!
Thank you!!! You comment means the world to us T_T
Oh my, the art looks even better than in your previous game! I usually don't like yaoi for too cartoonish or feminine look of the male characters, but this one looks great. And tentacle monster.... oh my... Cannot wait!
We're glad you like the art! It was drawn by 700HASH this time and they did a wonderful job with each artpiece. <3
A question. Would it be possible to choose MC's position (top or bottom) during intimate scenes when the full game is released?
You cannot choose their position, sorry. Whether they top or bottom is a plot point in several scenes and it would feel unnatural to let the player choose. You will however be able to skip any NSFW scene you don't like when they happen with a simple button.
Is there a special r eason why it's released on the Ides of March, or was that happenstance?
We decided to release the demo around this period of the year back in November 2021. Actually, our original goal was to release the demo and launch the Kickstarter on February, but due to various circumstances it was pushed back to March. So, to answer your question there is no particular reason aside from being sure we'd be ready by then.
is the demo nsfw?
There will be 2 versions of the demo when it goes public: one them will be SFW and the other NSFW.
Unlocking Demo costs 20$ on Patreon?
Hi, there! Thanks for asking the question.
The demo will be public at some point next month, but for now it's only available in our Patreon in the $20 tier. Making a game, especially a quality, adult game is expensive and this demo alone cost us $6000 USD to make. Our patrons in that tier will also get access to new chapters every month.
In the content disclaimer, I see that there are tentacle sex. Will the tentacle sex scene be avoidable, please?
Hi, there! Thank you for your interest in the project. 80% of the adult scenes have tentacles in them, so they are not avoidable. However, The Symbiant is a story-rich game so we are also making a SFW version of it so people can enjoy it without the adult content. :)
Also, just in case that's what you're worried about: all the tentacle scenes are consensual.
So hot!!!
hot
Oooooh yes alien boys~
Oh wow the art looks really good for this I'm very excited.
Oh, I'm really looking forward to this! :)
Sounds good! :)
