I like caves that are relatively straightforward and can be solved without a big deal of frustration or luck. I'd hate BD2 cave F if you had to collect all of the diamonds... And BD3 cave K bugs the out of me...
Boulders are round.
Fireflies are square.
I need to find
a'way out of here.
I'd like your cave, too
I'd like to see a cave where at first sight, you don't know how ever to finish it... maybe there are 14 diamonds obviously, but you need 15, or sth like that... or 5 butterflies and 46 diamonds required...
I love this idea to get 37 diamonds in BD2, cave O (see topic BD2 discussion)!! If I didn't know the answer now, I'd love to try it and desperate due to this 37st diamond...
