Very cool style, it's a neat little roguelike style game. Boss was cool, and the animation at the end picking up the orb looked really fluid. Bunch a little things in this game added up to something real neat, and I would love to see this game expanded on!
My only critic gameplay wise was I felt the depth perception was a bit weird for me, were I couldn't really tell sometimes if I was inline with the enemies enough to hit them. This could also be alleviated with a bit more impact on hitting the enemies.
