Nice game, very creative way you managed to implement a great boss battle with simple yet pleasing graphics! I didn't really get if I was doing any damage to the boss at all or how much life he had left, or at least I missed it. Maybe implementing some kind of heal bar ?

It's a little bit hard to figure out how the game works at first, but once it gets going it's great fun. The aesthetics and gameplay reminded me a lot of the good ol' flash games of the past.

The concept of just the final boss is a great spin on the theme! I was a little confused on how to hurt the boss, however. Great controls as well!
