I decided that rather than flood the forum with another thread, I’d use this one. I’m stuck too, because I am stupid.
I’m in the Killer Bunnies level in the castle and came to where the block-like boss was. I killed the boss, got the key and left it there. Yes, I did not think to actually open the door, because that would have been too convenient, apparently. Well, I went back to check if I missed anything, saved (yes, I did mention I was a moron) and died. Now when I go where the door with the lock is, there is no boss and no key, but there still is a locked door.
I don’t expect anyone can help, as this is not a game feature but my own thickness that’s causing the problem. Leaving the area or reloading the game don’t help, as I saved the game after I beat the boss, before I died. But if someone knows of a way to get past this without starting a new game, I would be more than grateful. I too hit my head on the wall with couple of places mentioned on this forum before, so a thought of going through all that again makes me more gloom than your average emo kid.
Thank you.
