Cool little platformer! I made it all the way to the boss a few times, but I couldn't finish them. Nevertheless, I never gave in to hatred or bitterness. Visual and/or audible feedback when either the player or an enemy was hit would really take it up a notch—I didn't think my attacks did any damage at first until I (much later) realized that it takes two attacks to clear an enemy. Thanks for making and sharing your game!
