Always nice to see a game from someone, whose games I know I like :D
So again- good use of simple graphics, GREAT usage of music + health. Awesome, dynamic action! One thing- if there was more health pickups, the player would be more inclined to use the health-draining moves.
I didn't feel the jam theme, though. Like, yeah, there is some pickups, and health is also a resource, but you could have gone deeper with the theme.
Over all (as always :D), great game!
