4 riddles

A combination of four story levels type into one large level. One thing is that the ball drifts away from the desired resting spot as you don't have a wedge underneath to hold it. B then overshoots over the win not triggering it.

Spoiler

To ensure a ball stop, it is better to have a wedge under.

@ohmytian Thank you for your advice.
I'll try to fix it.

Relaxing & fun stars collecting gameplay... thanks @totto

Lots of fun! Four puzzles in one!
I really enjoyed working it all out. It's great that there are recovery points so that, if you fall off it is possible to go round and try again without having to restart the whole thing.
I did have the same sort of problem as @ohmytian , the ball rolled back so the B couldn't cross it.

Thank you for pointing this out.
I would like to post a revised version, but I don't know how to replace it.
