a few things, its a great game with a few minor problems. the colors are sometimes hard to see, as they are glowing and pastel. the other is that the timer seems to occasionally keep going when the level is finished?
theres just a few annoyances with the game that keep from giving is a perfect score.
i hate the UI sound and there rarely seems to be a hand that isnt either all columns or no columns with me playing the computer... still a great game. 4/5
the rocks you fire just dont seem to have any impact when they hit...
i could easily rate this game much higher, but the physics of impact seem a little bit off.
very nice game. it really reminds me of some of the old 80's shooters in the arcade. if you could upgrade a little more it might even be more fun. great music btw.
