I made one called "The Majestic Milk Machine."
Haha that's funny, without having read these posts, I played both your Majestic Milk Machine and Flaco's DK Mountain these past two days ... they're both quite popular now aren't they?
If you like the attention to detail in those, hopefully you will like this ... I will advise you to get used to how tight some sections are before drifting flat out though. It's from MotorStorm: Pacific Rift if any of you know that:
Additionally, you may queue it here:
Crab Canyon and Dance Floor Destruction.
Both of them has plenty of effort put into them. I always try to play and review levels of those that play mine.
I am also in the middle of making a ice ave themed level that's half way finished.
