And now, since I've played through Pacifica, here's a special GBA special of "Geno gripes about difficult levels, and attempts to convince everybody that enjoyment of these levels is what all this complaining is about"!
Stormy Seas - The level isn't that bad, but the Krackas hidden behind those window things and the water being stuffed with Lurchins were annoying.
Sunken Spruce, and Cliffside Blast - Both of these levels suffer from a distinct lack of DK Barrels. And Cliffside Blast has an Automatic Barrel Cannon that shoots you into a normal Barrel Cannon, with two Buzzes circling around it, which means that if you aren't fast enough, there is a 50% chance you will get hit, which is annoying considering that you can't see it coming due to the GBA's shorter screen (you'd think the SNES levels would have this problem, but nope! Mostly the levels MADE FOR THE GBA VERSION DO
)
Ripcurl Reef - Nice wind gimmick you got there. Too bad it keeps blowing me into Lurchins (which, like Stormy Seas, there are quite a lot of them), which usually results in Kiddy being murdered (I always put him up front, so that there is an even smaller chance of me hearing that terrible scream they gave him when he dies in the GBA version)
Actually, there's also a few complaints I have with the GBA versions of the SNES levels, although these aren't really "Most Hated", just "Mildly Irritating".
Springin' Spiders - The new method of obtaining the DK Coin is frustrating. I kept circling around that one area for HOURS
Every level with Ellie - What? They say that the GBA team tried to improve Ellie's controls. It don't seem like that. Being unable to suck up water is dumb, especially once you realize you need to hold R (the shoot water button) AND down, and even then, she doesn't do a thing until you release the B button, which I happen to keep firmly pressed down in every platform game.
Every level with a toboggan - See that bit up there about Ellie. Those new, floaty jumps threw off my timing in all the levels with the toboggan in them. Which sucks, because they were my favourite levels too!
Barrel Drop Bounce - Can barely see those barrels coming.
Krack-Shot Kroc - Oddly, it seemed EASIER on GBA, although holy crap Krosshair, CALM DOWN! We know you absolutely love the sight of spider guts everywhere, but jeez CALM DOWN!
Lemguin Luge - Is it me, or are their hitboxes for being jumped on smaller, and their hitboxes for killing you larger?
Bleak House - god damit, they ruined his laugh. Also, the snowballs you throw appear to be smaller, and unlike SNES, you have to hit EXACTLY where his target is to get him. Oddly, he didn't seem to ever go into the background...
Haven't got much further than Buzzer Barrage, but I can already tell that the issue of Kopters flying out of nowhere is only amplified by the GBA's screen.
But hey, I still enjoy these levels! Between the slightly off controls, and terrible new SFX, the port is the second best version of DKC3 ever made- wait a sec...
also frosty frolics gba is terrible
