Here's the kinds of levels and how many of them appear, to make up a total of 36+5 levels.

-6 Birdy Windless (Levels Warmup-5)
-5 Birdy Windy (Levels 6-10)
-5 Updraft (Levels 11-15)
-5 Jazz's Copter Tests (Levels 16-20)
-5 Airboard (Levels 21-25)
-5 FlyBoyy Tests (Levels 26-30)
-5 Darkness Tests (Levels 31-35)

And as a added bonus, if you beat my test you get to improve your rank by trying out 5 bonus levels...
-5 Copter Tests (Levels A-E)

This is only available in Single Player mode, not even CO-OP mode, if I can make this possible. Because Copters in Mutliplayer get messed up easily.

Have fun!

BTW: Original idea-Birdy Windless, Birdy Windy, & Darkness tests.

Darkness tests is a test where you are on a airboard underwater and you are holding a torch and you need to avoid all the grey tiles to win.

Hey, sounds good! Puzzle levels can be a LOT of fun if they're done right.

I forgot to mention that the FlyBoyy tests are also original even know it's quite simple. It's the solution to the Copter Tests problem, and the FlyBoyy carrot is better than the copter!

Thanks, for thinking the idea is good , Tetsuo9999.
