I actually played this game a few days ago, and IMO the game isn't that bad.
Besides the fact that fighting enemies is practically useless, and peeling stickers off walls every 10 feet gets pretty old.
Super Mario 3D land was fun, but it was so easy. Once you die more than 4 or 5 times on a level, it gives you a golden leaf that makes you invincible for the entire level. Then if you die 2 more times it offer's to let you skip the level.
Also i was kind of hoping for more of an actual landscape, instead of just random blocks and platforms hundreds of feet the air.
