so i played through the game again and the same thing happened with the red demon, even though i made sure he wouldn't block the doorway. also in the first cave there were some places that i couldn't get to though they looked like part of the game. there was a exp thingy in the first cave but i couldn't break it cause i had no weapon and when i got the blade i couldn't reach the first cave entrance. Also sometimes when you exit certain locations the mimiga town song plays instead of the creepy one.
