Okay I'll give my hints on the rest of the levels too.
Stamina:
Don't try the trap-launch if it's your first time trying to win the level. Do the normal path first, then try the traplaunch. Also, there is a helicopter hidden under one of the trapdoors on the left side. Use it.
Trigonometry:
Use the WR path. Also, use the SJ whenever you can. For example, use it to get every gem.
Slowropes:
Here's a tip I found: There are 2 checkpoints on a level. If you hit the first, it's the first checkpoint. If you hit the second, it's the second checkpoint. However, if you hit the first again, it works as a third checkpoint. Use this method to your advantage on that level.
Mastering the Marble:
Pretty much like everyone else. After the first checkpoint, it's simple, but takes patience.
BCF:
Just read my previous post .
I hope you find these tips helpful!
I love you, but your attitude is like that of a shrew. Your options? Take a pill or be my kill. Might I suggest that you wear a vest. Perish in class or be banished to the land of bluegrass, where dreams don't exist as you'll be eternally pissed.
