I found a glitch that allows for the player to just straight up fly.
Not sure if this happens with every character, as i havent tested it yet, dont even know if it can be done with any other character.
The glitch can be performed by getting caught by an npc whilst climbing a ladder. The player will then have the body glitch and the camera can look freely, even into the players body, the player is then in a permanent walking state that they can control by facing the camera in a direction, when faced upwards, the player can fly.
I have only seen this glitch once, where the mayor caught me whilst climbing the ladder in the greenhouse. Once flying invisible walls can be flown over and can access under the map
