To put it simply, this game just doesn't have what it takes to make a good platformer. Perhaps the most unfortunate problem is the insane difficulty. Enemies are ridiculously hard and sometimes downright impossible to pass or defeat. Platformers should be an enjoyable experience, not this frustrating. Other problems include a camera that is far too "zoomed in", making it difficult or impossible to time jumps or see where you're going. The game also moves rather slowly, making it a painfully slow process.
The entire game feels off. Rather than simply getting to the end of the level, you're forced to search around for 6 cages full of little critters in each level, making you play them over and over until you're sick of them. The added powers you get throughout the game are boring, the blue jewels you collect are worthless, and extra lives are far too few. Don't bother getting this game, it isn't worth it.
