I love how defined the characters are each one with their own thing. The art is also good to define them, specially on the skelletons, they really scared me the first time they showed up on screen. I was a bit confused by the exit button, I thinked it would close the game at the start, maybe another name would be better for that action.
I'd like also to give you a tip to get more people to play your game: specify the platform of the game so that people can download it and play it with the itch.io application.
