Hi ! To be frank, I didn't manage to finish the game... I did not understand how to kill enemies and avoid being killed. It's fine tho, from what I have red you can buy 2 types of platforms, so this can create interesting puzzles, the art style is great also.
By the way, do not mark your game as "playable with linux and macos", because you only put a .exe file with it. If you do so, explain to those users how to play your game on a different OS. (I am on linux so I knew how to do it, but It is not easy for a lot of people ^^)
Good luck on your gamedev journey !
