The game is beautiful and it feels nice to move around (nice sound design and animation) but the level design is kinda weird : there is an X and an arrow pointing down in the third level (i think) and going down only makes you realize you have to grab the key *before* going down. The time stop mechanics is interesting but timing it properly is hard (which is ironic), and it's kind of frustrating that there is always a sign telling you to use it and it is useless/dangerous (because you fall of platforms) to use it anywhere else.
I couldn't go past the fourth level because of nasty slowing down bugs, but it was nice to discover this little world. I really liked the cute/gore contrast.
