I like this puzzle. The game concept is inspired by
Snakeslider (http://members.home.nl/bas.de.reuver/files.html) or
TJ-wirggle (http://www.clickmazes.com/tjwrig/ixjwrig.htm)
the levels are stolen from 'block n roll', at least the first few levels since i didn't compare all of them

it was by my old account so it got disabled and i put it back on
