Very cool graphics and animations. The soundtrack is also awesome - it has depressing tones that matches the game perfectly.
I agree with other playtesters on hitboxes - they feel way off. It doesn't matter that mathematically they match the sprites - it is all about the feeling of touch. And I've got the feeling that I'm dying from touching the air instead of the enemy.
A little detail, but still - the gravity is also seems to be inconsistent. The masked dudes fall down very fast, but for some reason the gravity works differently on the hero.
