Nice graphics, but the gameplay is very simple. No sound. / thrust26

Very nice graphics, and fun to play. / Zach

Nice very progressive game. Some bugs seem to appear when a lot of rocks are falling (some disappear). / Euphoric

Another neato game idea. I had quite some fun with this! / Cybergoth

Very nice execution of an ok concept. Graphics are very pretty and controls are great. Sounds aren't great and don't add much. Real killer is that it starts off easy and takes too long to get challenging. / vdub_bobby

A pretty good implementation but the gameplay is very repetetive and it takes a long time for the difficulty to ramp up to the level where the game is a challenge. / Matt_B
