Experience the romance, drama, and mystery of humanity from the outside...

In a future where humanity has taken to the stars, and where alien symbiotes can  temporarily share a willing human host's body, play as an alien thrown into the middle of an awkward romance and mystery.

The Ishin aliens have the ability to transfer their minds into willing hosts - sharing the space with the existing consciousness.

The first host is a shy, in-love bio-engineer who hopes the alien can give him the confidence he needs to ask out the person of his dreams, but things don't go as planned, and when the alien returns to the mine base and into the second host, it's for a much more urgent, and darker reason.

Part one of the game is available now, and covers the first half of the story. The game will be updated once the rest is complete.

This was a lot of fun! I loved discovering more about the world building, and the twist at the end has got me eager to see what happens next, :D. 

i need this game I'm so glad it's almost october. how much will the full game be?

Thank you for your kind comment! :)
The game was always planned to be "pay what you want", so we'll be keeping that for the full release

I really think your work is worth a fair set price just throwing that out there.


Really, really good... Realistic characters and an intriguing plot in a well built universe. Looking forward to the follow-up!

Thank you! We're glad you enjoyed the first part. There's a lot more backstory around the characters, Company, and aliens, and we're looking forward to sharing it.
