Working on Donkey Kong Country: Tropical Freeze right now.
Wow! It's not perfect, but it does so many things well that I can't help but love it. The level design is creative and really keeps you on your toes. I can't think of a game that's asked more of a player's skill, but I appreciate the high expectations. Retro put significantly more effort into the bosses this time around such that they feel like full-on levels. The music, composed chiefly by Dave Wise, is absolutely fantastic, blending atmosphere with diverse instrumentation and strong melodies... forming perhaps one of my favorite game soundtracks of all time. The backgrounds are full of life and the enemy design is wacky without being over-the-top or distracting. Combining the right music, setting, and flow, certain levels just seem to be "special" for lack of a better term—a really magical feat to behold. In general, I really feel like Retro managed to harness the "on your own" feeling of the original series and ran away with it, producing a product that well surpasses Donkey Kong Country Returns and perhaps even the original Donkey Kong Country (though nothing will beat DKC2 in my mind for nostalgic reasons).
But like I said, the game isn't perfect. The bonus rooms get stale right off the bat. The controls can feel slightly unresponsive at times, especially with the "grab" motion and the chore of swimming. It's frustrating how the game places a number of KONG letters at places where they become irretrievable if you miss an opportunity to grab them at first, forcing you to take your own life if you want a chance to 100% the level. (The puzzle pieces don't bother me as much because they retain themselves between lives.) Disappointingly, many of these issues were present in Donkey Kong Country Returns as well; Retro seemed to stay with a formula rather than rethink their conventions.
But I feel bad picking nits. I think DKC:TF is a wonderful, challenging platformer that I would say exceeds Super Mario 3D World in its attention to detail, music, and general design. I'm certainly having way more fun with it than my last game, Xenoblade Chronicles X, which seemed to emphasize quantity over quality. I recommend Donkey Kong Country: Tropical Freeze to anybody who wants an old-school challenge in a game adorned with beautiful visuals and music.
