I had fun with the game. The visuals, live puppet show theme was quite well done. I had problems with them constantly interrupting the flow of the gameplay with never ending dialogue. Now that seems to work well in some other genres but in a platformer it becomes quite distracting.
The platforming in itself was not all that well done and i felt it was a game made to look like a platformer set in 2D space but didn't felt like one in its mechanics. The missions ranged from very cool to some never ending drags. The characters you meet on each of the levels were interesting and you could unlock their story and access it from another menu. It real like a dark fairy tail.
At times i was annoyed by Pikarina, the fairy companion but she was quite charming overall. So, in the end my thoughts were that it is a good game but not a solid platformer.
Another massive flop on PS3 as everyone went on and bought GTA5. On the other hand, Sony was stupid to release it so close to such a major game. Although, i appreciate Sony supporting PS3 and that i got to play this game. It would have been better as a launch game for PS4. I mean certainly a stronger game than Knack.
