Yeah,I know there were a couple of questions about this level,none of them answered my problem,so please bear with me. I decided to beat all the quests made by DarkFlameWolf,because her(his?) avatar is of Yuffie Kisaragi,my favorite FF7 character! 😃
First off,in the upper part of the map,I've found this room with a puddle in the upper part,in a small area surrounded by watter. There's a staircase next to it and I can't reach it. I assume you need the flippers for those.
Second,I foolishly used the first key I found to open another area. I know there's a room in the northeast corner of the map,but it appears behind a wall. For reference,there is a red bubble,blue bubble,and a bunch of blue Goriyas and Like Likes. Killing all the enemies makes the key appear. Is there any way to get to it?
