Great game! the action is intense and is very well served by the music! I like that there is a variety of enemies but also of actions, dodging, aiming shooting. Maybe I would have liked to have and indication of my time when i beat the game. That gives an incentive to play again and beat your previous time.
Also, thank you so much for adding arrow controls. My keyboard doesn't have a qwerty layout and there are many games I can't properly play because of the wasd only inputs.
