The graph may well be drawn with love, but really talented the artist is not. The screens are never overloaded, and real fun will not be set. Why do I lose when star the Sandman runs against an obstacle, floats or whatever he does, also not open up to me. Somehow some sort of difficulty should be introduced so. The requirement may rise at higher levels yet, but so far I did not manage. Judging by pure puzzle games like Wake the Cat or Cut the Rope is back and forth of the levers and platforms too simplistic and considering jump'n'run platform or playing the game well, to fall asleep.
Who the graphics from the screen shots like that matter, can strike here. There are worse games but also much better.
If you like puzzles to Wake the Cat should view times and if you like platform games should perhaps look at Rayman.
