Been playing this some more. Since getting a better handle on the controls, I'm enjoying it a lot more. The level design is really good, and the challenge, for the most part, is solid but fair.
I'm still dying to the rolling, but very very rarely. I do still wish it was a button though.
I have to say the game reminds me a lot of parts from the Mega Man series and the Wario Land for Virtual Boy. For the former, you have various moving pillars, including some that smash into each other or just run straight from left-to-right across the screen. Some of that is straight from Mega Man. Also, there's a section where various planks pop up to reveal cannons, and you're meant to jump on the planks that become platforms. This reminded me heavily of the "disappearing blocks" sections of Mega Man since you have to memorize their order as well.
Wario Land VB memories come from just how many obstacles come from the background to the foreground. Actually, this game is so beautiful that I'm glad Nintendo didn't try to quickly make this a 3DS title when they realized how much Retro was using the third dimension. The Tidal Wave level as well as some levels with rolling spiked balls are very clever. Anyway, you could certainly pick two worse games than Mega Man and Wario Land VB to draw inspiration from.
Speaking of the Tidal Wave level, that was unfortunately the only time I got a sense of classic DKC "mood music." Although the music in the Cliffs also has a "feel" to it. I know it's an intangible, but most of the music hasn't lived up to the series.
Still, what Retro has accomplished is really impressive. The clinging mechanic was a great addition. They've also taken the series staples, mostly barrel usage, and truly pushed the creativity in using them in crazy unique ways. Not my favorite platformer on Wii, but a fantastic one for sure.
