(Wii version reviewed) MP2 features a dark world / light world setting which I find fascinating and amazing! It adds a lot to the atmosphere - speaking of atmosphere, if you are in the dark world, you constantly get damage which is in my opinion a great idea because the player has to figure out new strategies to complete a room without losing too much health. Graphics and soundtrack are top-notch just like in the predecessor. There are many things to discover via the scanning feature which is really fun to use. There are also some cutscenes which tell the story - that is something that I missed in the predecessor. All in all, I find this game better than the predecessor although there are still some annoying things. There are too many morph-ball-"minigames". The Screw Attack is difficult to use. There is a camera glitch in one room. The final battle - which has a freaking TIME LIMIT! - is very unfair. Some enemies get annoying and repetitive. Great game, it's like MP1 done better!
