Nice design, unsure about a few things.
FIrst thing to ask, is there a lose condition? I found my first run of the game fairly easy, so I let myself get swamped by enemies and... Nothing happened. It ultimately removes any challenge from the game, which is a shame.
The enemy, player and scene designs are really well-done though, however the animations are a little minimal in some areas. I'm unsure as to what the "jab" animation is actually meant to be, as it's on the hand that's on the other side from it's hitbox?
Aside from this, the game was nice to play. Well done.
