Donkey Kong Country Returns came out yesterday. I played the first island part (1-1 to 1-6) and passed the first Boss. You collect bananas/balloons, spell Kong, find hidden puzzle pieces and areas... it's like 15 years ago.
The first art deco type level -- all in the shadow of a sinking sun was fantastic.
As for difficulty level, there are some difficult spots, which I'm sure will ramp-up higher in later levels.
The forced motion control (motion down for ground slap) is more of an annoyance than an impediment.
As if there were any doubt, yes, it's awesome so far!
