I think there already are some games, or at least interactive things, that let you do that. It sounds like it would be pretty easy to make. Do you want to describe it in more detail? I might be able to help you with it or something.Quote from funnyavHmm. I've had another idea for a game. If anyone knows the game "Gravity Atom" where you click to place an atom amongst others, and then it goes towards them and if you put it in the right place, it orbits around them and only hits them AFTER the time runs out?

Anyway, my idea was to make a game like this, except you can move them around, arrange them, make them bigger, increase their gravity, and THEN click somewhere...
just a thought...
