I can't give this too many stars because it's not even a finished game.
Helpful notes:
-The door's entry area is too big. Instead of actually entering the door, you just teleport inside once near the door. I can see this becoming very annoying if the game is larger and there are many doors to accidentally fall into.
-When inside the house, I suggest a different font (thicker and bolder) as well as a different color. Black on grey is very hard on the eyes, especially in an RPG where there might be a lot of reading. If you want to use whatever color you want you can always add a dialogue box. That way you won't have to worry about different terrain colors messing up whatever font color you chose.
