Great game! Unfortunately, there's a bug. It was this stage with the ??? powerups in the first few stages.. i think it was stage 4. I got the shooty powerup thing and shot away to destroy the blocks not protected by the metal.. then one red block stayed up there (unprotected) it just froze there and didn't get destroyed no matter whether the ball(s) or the laser hit it or not. So i couldn't complete the level. Just that small blip.. other than that.. great game! Loved everything! the graphics.. the gameplay.. everything.
