You have to learn to get used to the sounds
This was a fairly enjoyable game and I think it was good, if not the most addictive. The design is very simple, but it is a pretty interesting concept. It's nice that you are able to show what Newton's third law is like, by educating us as well. It was interesting how you used a lot of music for this as it was good music to begin with. I do say that the design looks like it needs something, like better color effects. While not the greatest, it's a simple little game that seems like Pong or something.
