Neat little platformer. My main issues have to do with the controls. Mainly that they aren't explained. The least you could do is put the controls on the game page. I had to guess and check to figure out the controls. Because of this I got stuck very quickly probably because of a button I didn't know I had to press. The art also is a bit uncohesive. Most things are fine but then the bats are like a different pixel type and the UI is normal nonpixel art. Like the game would look ten times better if everything lined up better. But the rocks smile did make me chuckle. I would also implement respawning as game over after 3 hits is quite ridiculous.
