Hey, thesacredlobo thanks as always for playing my game and uploading these :D
I've been replaying this game too, and I'm not sure how far you've gotten, but I found a game-locking glitch that's possible to encounter. After you get the airship, if you go to the town/temple on the Etherlands before getting the key to the temple door, the game won't let you leave back to the overworld ;_;
EDIT: I've uploaded a new build that fixes the problem, just in case you or anyone else happens to get stuck there.
