Good, however it is a little glitchy..
Initially, I wondered what the point of this was. It was just a game about picking up a ball and bouncing it. Then I noticed 'Press h for help menu'. I was amazed at how much work was clearly put into this. It's the most extensive bouncy ball sim I've ever seen, and it's the type of thing I myself could sink hours into (Not sure if that's a credit to the game, or a detraction to myself). Assuming the former, it's pretty good. It's the kind of silly distraction that we just don't have enough of here on NG. I really quite like it.
The premise and appearance are deceptive to the surprising depth beneath. Supported.
This kep me entertained for some time. But why this can't bouce off wall ?
It is an interesting little bouncy ball thing, but if the purpose of it isn't a tutorial I don't understand why you posted it.
While I'm sure you put some effort into it I think this could be great if you showed people how you got to the final swf.
