I gave it three stars. It has some great animations, nice chillout theme, but the puzzles are too easy and the game is simply too short. Good one-time experience.
Nothing realy special. It's similar to Samorost when it comes to game mechanics, but not even closely as good as that game. Also I don't like the idea of provoking all this gory events which it presents.
It's pretty good game. I have not yet played the first three parts of it, but this one has quite easy puzzles. I gave it four stars because how short it is. With some experience with this type of games it should take less than two hours to beat.
Not bad, three stars from me. Slashing mechanics is well done and prety entertaining, but there is almost no challenge in the game as a whole. You may get some points for killing enemies, but there is no score board at the end of the game or anything like that, and the best (and prety much the only) way to refuel the life bar is to die in battle.
