object, but it didn't
I loved the voices and cheers, alongside the way you use the variable sound volumes to indicate when we're slowing down.
The 'fast' tune did get a bit dull after a while and even when the blue bar was at the top, I felt like I wasn't moving as fast as I'd like. I reckon maybe you could've had more major speed-ups at the start and allowed them to boost you beyond that point, wherupon you'd zoom to crazy speeds. Or maybe just make the x-speed faster all the time. It wouldn't make the game any easier - only harder if anything, as we'd have less time to react.
I think I'd have personally enjoyed it a lot more if the acceleration was faster (in the y-direction). I felt like often, if the speed-up was on the other side of the screen, even if I immediately started moving to it, I'd still miss it. Staying in the middle is not always an option, with the rocks.
Also, with certain formations of rocks, I felt like the random number generator was more at fault for my performance than any actual decision I'd made or whatever.
Maybe if the speed-ups were always in the rings, that'd help eliminate the feeling of chance, as we'd have more of a 'warning' about where it may pop up. Although that may make it too easy...
I did notice that folk have gotten 3x my score and I'm not sure how much is due to skill, how much due to perseverence and luck, but I'm guessing a majority of the latter.

Fun for a while, with great use of sound and voume control of the sound object, but it didn't have as great a sense of speed as I'd like and felt like my failures were often the fault of the RNG and the sluggish controls.
