Beat this game and mirror mode a month ago and absolutely loved it. I know Neogaf seems to be fairly split on their opinion o the older DKC's, but for me personally I've been wishing for a return to the series for ages and this was almost everything I wanted from a DKC4... And since it's DKC
Returns, it wasn't obliged to build off everything (worth building off) in the previous games either. I think aesthetically speaking Retro hit a nice sweet spot between harking back to the old game's environments while injecting their art team's style into them. It really does look like what you'd expect DKC to look like if it were made 15 years down the road, unburdened by plastic-y CGI or the SNES' limitations.
However while I doubt I'm the first to say this, but aside being piss easy by the time you tackle them in time trials due to muscle memory, the jet barrels are pretty awful. Completely divorced from the rest of the gameplay and personally seems to slow the game down way more what with the amount of trial and error dying than the cut water levels (which they could have just made Enguarde-only which would've been nice since I liked Retro's redesign of Rambi) would have. Feel the complaints about waggle are far overblown, though it seems odd a lot of the online marketing seem to focus on people revisiting the older games via the Virtual Console if they were going to change the control scheme that dramatically.
Would kill for a DKCR2 in a few years time; just give me more animal buddies, get David Wise on board and throw in a few more familiar faces like Funky and Dixie and I'm good to go. K. Rool too (apathetic about whether he comes back with Kremlings or not) if they're struggling to think up a memorable final boss like they were with
. Rest of the Tiki's were awesome though, and like the pirate Kremlings of DKC2 were built around the game's theme very nicely. Be neat to see what else Retro could think up if they don't revisit/redesign the Kremlings next time (though I sort of hope they do). While I felt in DKC the Kremlings felt tacked on (though I still liked the Zingers and Necky) and in DKC3 they just looked flat out bad (not to mention they didn't bother to line them up with K. Rool's mad scientist persona of that game).
EDIT: Returns didn't have any personality? What? Besides Cranky not really breaking the 4th wall anymore or having someone as over the top as K. Rool as a final villain, I felt it was very inline with how the older DKC's, just updated a bit. Honestly, it's pretty impressive considering both how very little people on the project had prior history with the earlier games or considering the difference in styles Retro has to early 90's Rare how nicely DKCR fits in with its predecessors.
