Wow this game looks really cool, but there is no browser or mac version and I have a mac. You should consider adding one, because this game looks fantastic!
Okay, funnily enough, it seems your game was made in Godot, which is what I used to make my game, so the download opened the game and let me play it through a Godot test window! The game is great btw, the ghost's animation and the physics based puzzles are fantastic!
