I played it without reading the instructions (my bad) and thought it was pretty boring, but when I went to close it I saw the part about speeding up when matching the red and white lines. That's actually a great mechanic! Flying through the sky water is pretty dope.
Have you thought about making courses / tracks / levels to play through? Maybe collectibles floating in the air? (I thought you could nab the colored specks.)
Anyways, good stuff! Very reminiscent of old flash games.
