I love the art. The animation for blinking is nice and clean. While I do enjoy the wide amount of action options (you even put in a crouch jump!), it's easy to have wires get crossed when playing with the keyboard. Personally I'm just not great with the keyboard though, so take that as you will.
I dig the way you can fight everything but you don't necessarily have to with blinking. That's a neat idea for sure. This game is HARD, those hordes do not stop. I'm gonna keep trying until I can at least get to the boss. Cool idea and well executed.
