Wow. You work way too fast my friend, way too fast. Maybe I just work way too slow? ;o
On a serious note, I see you got that green rock thing, whatever the hell it's called. That's such a trademark from Banjo Kazooie, and it technically makes the stage "not flat"
To be honest, I don't give a damn if the stage is flat or not. I love Banjo Kazooie, and your work, and that will not stop me from downloading this.
I also noticed you edited Gruntilda's picture and gave it better quality. Nice job Mewtwo!
I guess I spend too many hours, that's the thing xD
Thanks for your words, I hope the stage is good enough to make you enjoy. Also, you've noticed the green rock to be part of the gameplay with just a bad aerial picture, nice on =P
And same to Grunty's picture, I didn't guess anybody would be able to notice the change with just a few preview pictures O.o
By the way, I've just recorded the first video. The stage isn't finished yet, but it's complete enough to look like finished. Only a few black zones appear sometimes when the camera is zoomed out, or too low.
I'm gonna upload the video in a few moments, will post it here when done

EDIT: Done xD
