Your npc.tbl is broken. All the enemies (at least the critters and the bats in the first area) no longer have hurt sounds or dying sounds. You're probably using the latest version of CE, which has a glitched npc.tbl editor. I forget which version had the fixed npc.tbl editor, though.
It should be in about a week.
Also, you guys mind if I have endings without credits? I still have no idea how they work. I have a different idea, though.
Sexplosive is right. It will definitely not be finished tonight, but it'll probably be finished by sunday.
Of course, that's without the new music for it, but I'll upload 1.0 before I put those in.
so i just found a 1x1 tile hole in the roof of the Mimiga Village above and to the right of the entry from First Cave
EDIT: assuming that the snaking water maze thing in the bottom right corner of the Mimiga Village is designed to keep you out of the Egg Corridor until you get the airtank, it's not long enough. needs another couple of tiles at the start, or a fast enough person can get through it with like 2-5 points of air left
