I really liked the progression of the game with the additional features as you beat a boss. I did miss the ability to just have all the tools during beta testing because the gravity skill was amazing when trying to clear levels. The interface was also very cool. I liked that you could visually see all your abilities and their cooldown with the fade. The speed of the game was also very cool. One thing I did notice however was when shooting, it would pick the direction that was last moved. after a jump or an up arrow key, I would expect the shoot direction to be either left or right depending on the idle position. I guess this does add to the shooting directions, but I found it a little weird trying to kill enemies.
