Hey, thanks for the review!
I used the pre-made engine of RPG Maker MV, and couldn't actually find anyone who would do NPC or player sprites in time, so I just stuck with the original assets. The Tilesets from LumeZu did come with a character creator, but I couldn't find a good way to format it into RPG Maker's spritesheets, and had to go without.
In later updates of the game, I might make it so that using the Hypo Umbrella will move you to the other version of the room - meaning if you're in the tent, you'd go to the Hypo Realm's version of the tent - but that alone will likely take several days to do. (There's about 30 rooms in total, and I don't know how to do it without hardcoding each individual room.)
