Really impressed me conceptually. I'm not used to combining shooters with drawing speed. And it was fun! And the music did pump things up at just the right moment.
My main question is about interface. For the drawing, I kinda wish I was playing on a touch interface. I don't like the mouse for a drawing implement. But even to navigate at all, I was using WASD, mouse for perspective, mouse click for shoot, and mouse draw for special powers. It got a bit confusing to (for example) use the same control for perspective changing and drawing. And I see no reason I couldn't have used, say, space bar or X for shooting. I suspect perspective shifting will matter more later, but in the limited amount I played, I didn't really need it. I'd have rather had it auto-zoom on the character and shift perspective as he moves.
Overall, I had a ton of fun in a short period of time. Just as you don't play puzzle games, I don't really play shooters, but I respect what you did, and would play more. Might still. :)
Leaving you a five star review as well.
