Fun, but short. I think there should be a quick-restart keybind. I also wonder how the game would be if it relied on accuracy with puzzle mechanics, rather than quick reflexes (what the timer encourages)? For example, a level with 2 bullets and 2 bounces: shooting a button to open a door with one bounce, and shooting through the other, bouncing, and completing the level? Per-bullet bounce counts could also be worth considering. Just my thoughts. ^^
