I like the Paper Mario like style, but I am not a fan of the camera angle. For me it was hard to judge certain jumps and whether something was in the background or foreground. There were times where I died, because I thought something was in the background, but it was just higher than the other objects.
The tunes were really nice! And I think the power ups are well chosen.
Unfortunately, I wasn't good enough to finish the game. It was too hard for me.
