>Would that be enough?

Honestly no, the windbag is quite tricky to learn. Actually when I started playing OpenClonk I didn't know what to do with it until I saw other players use it online.
And after that it really took some time to master all the jumps, so a simple level where you have to jump around, while each Jump increases in difficulty slightly would be very helpful to newbies, and in fact to me too :D

Actually yesterday when I played, I still died because of timing those jumps wrong, so I felt like I really could use such a level :((
And don't get me started on deflecting objects like rockets to attack, like K-Pone uses them, though that sorta stuff could probably go into the Tower.
