Alright - got an almost-final list, but it has 33 levels. Out of the levels on it, I'd like to - if anything's going to be dropped (which one has to be) - drop one of the following three:
LPO Mental 3 “Doomblock 42”
LPO Mental 12 "Cave of the Cactus"
LPIV Twisted 16 "Don't Hold Me Back!"
Any comments?
I also put up a poll. I'll make the decision based partly on feedback, and partly on where (if any) there are gaps in the difficulty curve - I personally feel that Mental 3 and Twisted 16 are of similar difficulty, while Mental 12 is a fair bit harder than the other two.
EDIT: Sorry, my bad! I forgot to update the list taking into account the suggestions a few posts above first. I'll consider that, then see if further feedback is needed.
EDIT: Even after considering that list (alongside other suggestions), it still comes down to 33 levels, with these three being the ones to decide between for removal. I'll now review the ordering to create a good difficulty curve, and if there still needs to be a decision on which one to remove, I'll put the poll back up.
EDIT: Okay, after taking difficulty into account - Cave of the Cactus is safe. But I need to pick one of the other two to remove. So I've put a poll up just between those two.
