Glad you enjoyed the game.
I very much did use MV default maps for the most part. That was a decision I made at the beginning of the jam because I wanted to focus on gameplay and not get bogged down creating maps. Some have minor to moderate edits, but every map except Jade's room, the guild rooms, the bee field and the ship are default maps.
Thanks for mentioning the bee glitch. I was tweaking the event mid playtest and forgot to fix it before uploading. I'll be sure to tweak it.
