Inspiring concept, fun graphics and cool music.
It was a great idea for the use of the limitation and theme, but for me it felt like it kind of missed the mark.
I can't see the bullets bouncing because the screen is so small, and since they are endless... After a while I don't really feel like they are my bullets... just random projectiles coming from outside my screen.
And since I don't have to paint all the blocks or even the walls, I didn't really felt like I was doing something to paint the room... It was just happening automatically.
It was interesting though. Good job for 3 days.
