Hello guys, I've seen some speedrun of dkc2 and I'm amazed of how fast you can beat this game, I had so much trouble with when I was a child. Shouts out to all speedrunners!
When I was little I recognized something, I had a pretty strange glitch I've never forgotten. I started a new run and made world 1 all 100% then moved to the second world. And when I payed that Kremlin dude to gain access to the secret word and Bam! I was able to fight K. Roll in the "final stage". I don't know how I accessed it, but I'm pretty sure you know how to find out. I don't know if this helps you, but I registered just to tell you :) hope you can do something with this information.
BTW I didn't die 1. World but died after some tries to K. Roll. And after reloading the game, I didn't have access anymore. I can remember it so good because I've never seen him in the lost world before.
Good luck guys and keep running :)
Anything game-specific, you're gonna want to discuss on the forum for the game itself. Or nowadays many game communities also have Discord servers. This forum is at a site-wide level, and you're quite unlikely to encounter anyone with knowledge of your game.
