The loop is fun! Movement is too fast for such a small screen and some movemements feel too sudden, like the knockback on bats, they even get knocked outside the screen. There's pumpkins being damaged outside the player's view without warnings.
Most of the problems with the game are because of the screen size. The art is good, there's an effort to build a world surrounding the game, and the loop is enjoyable. Overall a pretty good entry :D
Viewport on itch doesn't match game resolution and using fullscreen gets you a black background without actually making the screen bigger. I think you just have to set the viewport on the edit page to a bigger size so the game fits inside :)
