Not really different with Loops of Zen in essential. No skill needed when you know the exact algorithm. A time counter would make this kind of game more exciting. It's just another tedious rotating advanture now. 2/5 for no real improvement from old game.
Awesome game concept! It would be nice to have a level editor though.
@Sketh: You can use recursion in this game. The level ends when all blue floors are lit AND "a function ends". That means you can put both F2 and F1 command in F1, and the level will end when F2 ends, causing no problem.
