Not bad, even tho there are little technical details that can be improved!
-When you have your sprite click the source image in assets and in the settings of the inspector change bilinear to point (no filter) (so you have nice unblurry pixels!)
-Appart from that i found some disbalances between the skeletons and the mushrooms (lmao they moved like crazy sometimes xddd) so it would be nice to do more balancing (it's a jam tho, my game isn't done at all so i canno't complain hgahahah)
