Just saw your game over on kickstarter it looks amazing!

Would you be interested in looking for a junior sound designer? Composer?  I’ve got a few tracks that could give you an idea of how I write my music. 


I’d love to compose some original music and or help with sound and foley if possible!

Please reach out if this sounds useful for your game! I’d love to see your creation come to fruition.

I also have a demo reel of a game trailer I’ve done if you’d like to see more of my work.

Hello and thanks for the comment & encouragement, they mean a lot!
If you're up for giving it a try, we'd love to hear your feedback on it. The game is still very much in its prototype / experimental stage, so there is no need to be gentle about it

Great Game! It contains many expansion options that drive you forward to play. Keep it up =)

Thanks for giving it a try, any kind of feedback is welcome!

Installing on itch.io desktop doesn't work, I'd paste the error text but itch doesn't let me highlight it.

I made a small fix and re-uploaded the file, hope that does the trick!

Works, thanks!

No problem at all!
Any first impressions?
