Long levels in CCLP1

[Hornlitz]

The thing about long levels is that if they get boring (coughcoughontherockscoughcough) they are bad, whereas if they keep their fun value throughout, they are much more fun to play. I have quite a few easy but very long levels in my set, but each room has a different challenge which keeps things interesting.

But multiple puzzles and challenges in one level might be too hard for a beginner, especially if one or more parts consists of something mildly difficult to beat. Ergo, A not too long, one or two idea level would be fine for the set IMO.
