Old concept, but for once a decent addition
Now I can't argue with TheRealSalkind below. He's right on every point. Music, a must. New shapes and the such, take what he is saying seriously. But I do want to add this, I have played many avoidance games like this and many eat or be eaten games as well. This is one of the few that not only do you have to fight the other objects, but the environment as well. I like that. Not only do you need to work to avoid the bigger cubes but now you got to worry about fighting a current that keeps trying to push you away which adds to the challenge of trying to avoid those nasty cubes if they push you into a corner. For your first attempt I must say you did a wonderful job in your programing. If you can pull this quality work out while new, I can't wait to see what you can do when you get some experience under your belt.
