It's brick breaker, only the blocks respawn.
Uh, what did you do in two months?
It looked like crap when I first put it out.
PR1: No main menu, no score, no health, it was just you hitting the bricks for nothing. Once you lost a life, you were through.
PR2: Main menu, looked like crap. Score, health, and time bonuses were added, but it was buggy.
PR3: Tons of bugfixes, general imagery improvement, FPS would show up if it would drop below 52/60, and the high scores were integrated into the game. Co-op was nearly done, but still not working properly. Also, some other things were improved.
