Nice mechanic with the fist. I didn't read about hitting both fists at first so I was a little confused. The art could be a little improved but at least it was consistent. It's great that there is a boss fight! 

I like how the game favors accuracy over reaction speed with how a missed shot leaves you open to attack.

I was stumped at the beginning on how to start the level, adding in direction in the game to do so would help that hiccup.

Hi well done for the implementation.

The game is quite fun to play.

That's nice that you have add a boss fight it add a lot to the game.

Maybe next time team with an artist it will benefit your game a lot as your gameplay is nice and controlls are fun.

Also for next time add a small tuto to help the player understand how to start the game (without need to read the description of the game)
