The concept is really worthwhile! I'm rotating like in the Matrix movie! Understood about 2d mouse after a minute of play, before it I only moving horizontally. After this game become more cooler than it was! This was really fun! Animations of enemies is really good.
I think level can have more props out here to become more pleasant to eyes. But anything else is great!
Next jam try to export with html, so more people can play just on site. I think cocos2d can do this!
