This is an interesting mechanic, and I like the Arkanoid+Tetris kind of feel, but I have NFI what's going on. Why are there lasers? What determines how much lasers there is? What determines where the start point will be on the next go? A bit of explanation and polish could really make something great here.
The ball shaped powerups add more bullets, the rectangle shaped powerups increase laser strength. Starting point is wherever your first bullet returns.
