Wriggle Worm by gikdew 2014-04-29T20:35:00
I really like the bold colours and sweeping curves of the worms, and the white noise does give it an airy, ethereal feel even if the mechanics aren't exactly relaxing.
I'd be tempted to suggest that you go full Flappy Bird on it and do away with the health bar entirely and just have the game end on your first contact with another worm or the walls.
Also, you could give the different colours of worms different behaviours to try to mix up the challenge a bit. Maybe have orange worms do a loop in the middle of the field before leaving, and have red ones aim aggressively for the player to stop camping out in one area of the screen for too long.
