I succeed to finish the first level but it was hard!
I exit on the second level as I can't see a thing, all is very very dark (on the first level also, and it make me fall a lot)
It give me the impression to just turn and turn around until I find the solution. Maybe more information could be better (ex : what is the next face if I turn right or left. I enjoyed seeing next face when I go up)
But the mechanic is interesting and it may deserve a more complete game!
