Excellent Game.
This is a great game. It tests dexterity, speed & coordination. It is frustrating at the beginning because of the minute scale, but that is part of the game's arcade feel, and players should really get over the collision factor, which is a +/- part of every game.
People who just play to win can just learn a few tricks and laze out for most games, but this game requires patience to get the right combinations for victory with both hands. Now, I haven't seen a game that held both hands rather equally and separately before, almost like a sport.
I would note one thing for the tenth point--it's conditional, because of the fact that there is no story or victory scene for people to feel accomplishment over. I suppose minor things like a victory scene, graphic, or dialog would make players a bit more happy to keep playing the game, and convince that the game deserves more 4's and 5's. Despite being the simple arcade, it has a really remarkably promising interface and level structure.
