I feel like the game has ages decently, but it has some problems. For one, the Rocketbarrels are ridiculously hard to control, the camera feels not so great; making it feel like I'm fighting it, mix that with the Rocketbarrel controls... Oh god.
Some of the Minigames are so frustrating! D: (Beaver Bother, The Beetle Races and The Owl hoop minigame.) And the collision and hit detection can be off too. (I got hit a Kasplat's shockwave when it was fading away, and I was nowhere near it. And I glitched through a wall and a slope in Jungle Japes.) Plus the controls do feel a bit slippery too at times.
But I can honestly say I did enjoy my time with it. I can see why people who grew up with this game love it to pieces, but since I didn't, I don't really hold those Nostalgia Goggles righteously for this game. (Except for Grandia and Sonic CD for examples.)
But at least this isn't the worst game Rare made.
I still feel like this game could've been improved on, but hey. We did get a rather good game. :3
