We're going to use it to make some rules only run on the first turn)

To make edges invisible replace the following four sprites with

. = Background
(We're placing our FirstTurn marker on top of the player, this way it will be there when the level starts playing since I assume you're always going to have a Player object in all of your levels)
P = Player and FirstTurn

HorizontalEdges = TopEdge or BotEdge
VerticalEdges = LeftEdge or RightEdge

SOUNDS

SFX0 43858302 (red sounds like fire)
SFX1 78429705 (the blue bubbles like water)
SFX2 36099700 (shiny gold)
SFX3 80750909 (bird sound as they glide through the white clouds)

======
RULES
======
(If it's the first turn, place one of each edge marker on top of the first turn marker, which is also where the player is!)
[FirstTurn] -> [FirstTurn TopEdge BotEdge LeftEdge RightEdge]

(These rules will move each edge marker over to their corresponding edge.
Since PuzzleScript rules are hungry each of these will continue firing until the edge is reached)
UP    [FirstTurn] [TopEdge  |] -> [FirstTurn] [|TopEdge  ]
DOWN  [FirstTurn] [BotEdge  |] -> [FirstTurn] [|BotEdge  ]
LEFT  [FirstTurn] [LeftEdge |] -> [FirstTurn] [|LeftEdge ]
RIGHT [FirstTurn] [RightEdge|] -> [FirstTurn] [|RightEdge]

(These two rules will duplicate each edge marker along the entire length of that edge)
HORIZONTAL [HorizontalEdges|no HorizontalEdges] -> [HorizontalEdges|HorizontalEdges]
VERTICAL   [VerticalEdges  |no VerticalEdges  ] -> [VerticalEdges  |VerticalEdges  ]

(Now we delete the FirstTurn marker, having finished our book keeping for the first turn we can get rid of it to make sure the above rules no longer execute on subsequent turns!)
[FirstTurn] -> []

(These rules check if the player is on the edge marker and pushes in that direction.
I'm going to use them to have different sounds play depending on which edge you bump into!)
[UP    Player TopEdge  ] -> [Player TopEdge  ] SFX0
[DOWN  Player BotEdge  ] -> [Player BotEdge  ] SFX1
[LEFT  Player LeftEdge ] -> [Player LeftEdge ] SFX2
[RIGHT Player RightEdge] -> [Player RightEdge] SFX3
