I'm liking the game so far, here are a couple QOL suggestions and a question:
Once you find an outfit or dildo on one of the floors, it would be nice if it became available on the ground floor so you can have them all available in one place. Also, since the number of floors is probably only going to get bigger, I think it would make sense for each to have a name that makes it easier to remember what stuff is on which floor.
I couldn't figure out how to pull out the gun except by getting attacked by a slime. Is there a button to equip it manually, and will you be able to use outside of the underground levels?
