Thanks for the feedback!
I'm not too sure if the thing with the Elixir of the gods can be done in RPG Maker, sadly, I'll need to look into it.
As for smashable doors, it's something I was planning on doing, but I wasn't really too sure what to do add behind the doors, so the idea got kinda scrapped. If I get some good ideas, though, I'll go ahead and add it.
