Ball Saver 49

[Ich_Flo00]

I did 4-9 with just 1 ball. Why isn't there an achievement for it?

7-2 can also be completed with one ball, but there's no achievement. Would be neat to get achievements for these, or at least to assemble a list of all the levels it's possible in.

7-4 is also possible to complete with less than available balls.
