This game is fun,but after a few days it gets boring and it seems like your playing different versions of the same level.So if your the kind of guy who likes adventure,I would not recomend this to you instead try Mario Galaxy 2 and not waste your time.
The game was ok i thought magalor was really easy after 5 tries. I don't like the game very much i thought there should have been more powers and that you should be able to have super powers like "Monster Flame" or "Ultra sword" to go on to the next level with. I thought that there should be more bosses and a lot harder bosses. This game wasn't my style i guess. If you get it, strongly suggest to beat all the levels first, then go back to get the energy spheres.
