i have meteos, and this is very much like it. a few things though:
1. you should probably put in some music
2. when the meteos come back down, make them keep going down slowly, not suddenly drop
3. you need to give them a BIT more thrust
otherwise, a great flash version of meteos!
but you should probably give a short VIDEO showing how to do it. its hard to explain, and i could tell some people were confused.
