Well, I just tamed the wild beast. Though I collected everything and finished with 100%, there is still plenty to do in terms of time trials, and another unlockable mode which, let's just say, would make a certain RFNer very happy. Those things, however, will have to wait for another time, as having finished the game I am relatively sated.
Which brings me to my point. I just feel completely satisfied. The game isn't perfect -- the inability to control Diddy Kong, the fickle shake-to-roll mechanic, and the lack of any snow levels (a personal favourite of mine) -- yet when I played through it, it provided an experience that represented with the very reason I play games. Things like the genuine challenge. I died A LOT, but I was only on one or two occasions was I on the verge of frustration. It never felt like doing something was impossible, but it didn't come easy. And things like the sense of discovery. Trying to collect all the puzzle pieces, which were hidden in clever and thoughtful places, was a blast. Sure, other games exhibit these elements, but this one just seemed to wrap them up in such a nice package. The highlight of the game would have to be the level design. There are so many cool elements thrown into each stage. In terms of imagination, it's on par with Super Mario Galaxy 2, despite the handicap of being stuck on an island.
I'd just like to mention the unlockable images and dioramas. Often such extras are just throwaways, but these are truly fantastic (the rather bland character sketches notwithstanding). The art is really, really cool.
Despite this game leaving me completely satisfied, I would love to see a sequel. Retro did an amazing job, and like Super Mario Galaxy, I wouldn't be surprised if some great ideas got left on the cutting room floor. If that's the case, then tighten up the controls and create me some bitchin' snow levels!
