A nice platformer! I like the obvious influence of Jump King without it being a copy. It would be nice to add in a little more control of some kind, like in Jump king you can jump straight up to sort of test a jump without committing, and because this game doesn't have that ability, it would be cool to see some other buff to the movement. I also like the more level based approach, so you can get the feeling of accomplishing a difficult section without the risk of losing a ton of progress, which Is great.
Overall very fun!
