Thanks for all the awesome feedback! Yah, I would like to adjust the physics to make the ball a bit punchy-er! Less floaty = harder without a lot of tuning, and in the time for the jam I didn't want to risk not getting it uploaded in time :)
Also, I'm curious is anyone noticed that when you are in "running" mode, the time on the board / ball slows to about 40% normal speed. It makes it way more manageable, but does add to floaty-ness a bit. I went back and forth a lot on whether to slow the music speed or do some other indication of this, but since you pop in and out so frequently I thought it would get grating.
Anyway, thanks all of the awesome response and feedback, it feels awesome to get some love :)
