Yeah, I know about the early Dream stuff, but I didn't really think about it at the time. The main development of BK would have been started later anyway Im guessing.
Apparently Fungi Forest was a BK level that was left over, so they made some changes and put it in DK64. I thought it was an ok level, but I didn't really like the day/night thing.
We probably should have gone a little deeper with the arcade stuff. Yeah, its kinda annoying you have to complete it twice. The second time through is the hard difficulty. I actually didn't have a super hard time doing it. I probably made it in under an hour all up, or just a little over. The animations were really annoying though, but I did touch on that in a more general sense.
As an aside, I finished the game the day after recording this. I found the end boss to be kinda cool, but it was annoying. Lanky's section was hardest for me, I failed on that a bunch.
