Very fun! I love how the enemies dont take damage when you jump on them! You actually need to punch them, which makes a lot more sense than that other game that is very similar to this one...
I also like how the credit is a level in itself, and the way its vertical is very fun for this style of game.
I would love some other enemies, maybe one that has a spike on his head which means you cant jump on him, but only punch him. or one that is bigger but slower and has more hp. ^^
Thanks for your comment Sam! :D
