The idea is nice, and the levels are *really* hard! Good job!
I don't know how does it work, it would be nice if you could integrate it in a "normal" level, like icy tiles to slip onto and normal (empty) tiles where you can walk - and turn

Zomis has already implemented something like this with an older version, I bet that now it could be made in a better way with 3.2.0.
(I knew of a game that used the idea above... Rescue Rover, maybe?)
"Slippery Ground" needs Rocks'n'Diamonds 3.2.0.
