I FOUND OUT SOMETHING GAME CHANGING
YOU CAN CLIP OUT OF BOUNDS WITH EARTH STAFF
it has to be very precise, and works best on areas where the wall - out of bounds distance is tiny. makes it really fun to be able to fight in such a big space if you aggro the enemies. maybe you can add a secret boss in the out of bounds? or a dev weapon or op weapon? after all, why remove it when you can make it a feature? and you could have the decision to make them out of sight or not to either hint that it is possible or just leave it in the dark, and i also didn't have to worry about getting back as i could either go in the same way i left or just end the room cuz it's accessible both ways
