It's a bug in the map north dungeon, after go down like 5 stairs, i don't think i was supposed to be here.
I wanted to follow the blue route, and i traspass this wall because i moved really quick with the dash. it's a little tile bug on the rmmv map creation
i'm sorry if someone alredy posted and the developer RyenSaotome alredy knew about this. I'm just trying to help
And thank you for this great game
