Nice Game! Really impressive for your second game! I really like the graphics! The jumps didn't felt that great and was a bit floaty and after a while the game felt a bit repetitive, maybe you could'Ve introduced some more elements to the game to make it more intresting. If you want to continue working on the game, maybe consider adding the stuff mentioned before and maybe look into the platformer toolkit, it has some great informations for improving the character controls! Overall, good job!
(Also it would be nice if you could do the same and rate & play my game too, I'm almost at my personal goal for this game jam ^^)
