Extremely negative I feel that constantly repeats everything in matches. You walk a few passages or paths along and then hits some opponents. Every now and then we must pursue a wall and a (too obvious) "hidden treasure" pick up. The gameplay is absolutely straight, you can not opt for alternative routes. The available attacks the skin character Knack are jumping very limited with x-key, with square slam plus 3 special attacks, but you can run only rarely, because you have to charge them only by collecting yellow crystals. suuuper monotonous!
The difficulty level can be chosen, but on "normal" already the game a real challenge! Cashes few hits you, you die and must almost even as far behind the current state of play re-enter that you can be up to 5 minutes play time playing through again. Unfortunately, there is no way to manually select a memory point, extremely uncool!
The game is extremely monotonous, because help is not the differently colored Level or the various opponents.
I can only advise against the purchase, unless you want to inspire a (school) child with this title.
This type of game is acquired otherwise from PlayStation Store for a few Euros as a download, to demand the full price of a must-have title, is an absolute impudence !!!
