This looks like it could be really interesting. The animations and art are very neat.
I can't quite read what type of experience the game is intended to give, but it is fun to imagine that different elements might respond differently when moved into proximity of each other.
I appreciate that you took the time to generate an AppImage. It's worth noting that when uploaded as single file, any executable permissions are lost, and it would be good to include that players should add executable permissions via the file properties dialog of their favourite browser in the game's install instructions.
Good luck if you continue development. I'd be interested to see where this one goes!
