Grunty's Revenge was pretty lame. The animation isnt as fluid as in DKC, their previous port (In fact, it even had more frames than the SNES version did) the view is terrible, and the game is like a step backward in semi-3D GBA games. Spyro did a much better job at a 3D game gone GBA than this title did. I hope Rare does better with Sabrewolf though...
That whole fence thing drove me nuts.
