Hi Awesomeness, thanks for trying the game! Just a few quick queries:
I found some issues though. The camera angle is set way too high and I couldn't see where I was going, even with the map.
Thanks! I did, in fact, have it a lot lower.. but my quite powerful computer blew up, and now I'm using a much slower computer.. I simply had to make some cuts somewhere, and by changing the view angle so that you 'saw less' the fps upped a very much needed 5-10 fps.
I should add the option to have it lower though, so that's something to think about!

Also, the biggest problem is that sometimes you don't bounce realistically. If I hit a wall parallel to my direction of movement, sometimes I'll go backward,
Oh, oh, backwards? That sounds like a bug D: Interesting enough, I've noticed a bug where the computers sometimes bounce backwards (in certain spots in the level..) but it never did for the player D:
If I hit a wall parallel to my direction of movement, sometimes I'll go backward, and the bouncing is way too fast compared to the acceleration, even of the fastest marble. If you just lightly brush a wall or graze it, you go flying off in another direction and it takes a LONG time to recover, especially since you tend to hit more walls along the way. I can understand using it to strategically bounce off corners to turn faster, but it gets in the way if you're not trying to do that. Maybe you could only make the walls extra-bouncy when you use the boost?
Yeah, here we have a kinda issue which I think makes an interesting gameplay match up. Boosting 'is' dangerous, and if your a fast marble, with good turning (but low acceleration) you may want to just 'race' around the track, where as one with good acceleration, or turning, or weight would want to boost as much as he can.
For instance, if you pick the cyan marble, chances are you won't really need to use your boost very much at all(to be the cpu anyway).. it's a very fast, powerful marble. But if you picked the black marble...
I know the bouncing can be frustrating if your not careful, but it's definitely part of the gameplay. It's a 'ahh, silly me!' frustration, I think. Well it's different anyway.
I got under two minutes in the world race and I couldn't submit anything.
Did it not ask you if you wanted to submit, or did the browser just not open? Oh, oh, this sounds like a bug report...
Overall it's really fun and I tried every race. Great job!
Thanks! I had an idea for a pinball theme (bouncy pads, etc) but with such a slow computer, making it wouldn't have been able to work very well at all... I'm just happy to finish it.

Do try the game's 2-player mode if you can, some of the marbles are unbalanced, so even if your a lot better than your friend.. the game can be equal!
