Donkey Kong Country Returns

Took me about half a year to beat it. Really fun game, although it made me want to explode with rage on some levels, it was quite a game. Beat it with 100% puzzle pieces and KONG letters but haven't done all the levels on Time Trials though, which I don't plan to do right away.
