(
It seems strange that everything is organized as APlayer then BPlayer yet
the starting player is B.

Also what's the motivation for picking some of the symbols? Like BPlayer is B but APlayer is T? Also a mix of
symbols and a letter for the targets. Would be nice if there was a clear pattern so it was easy to make and understand
maps. Something like A -> 1 and B -> 2 as targets in their own worlds. If their target is in the other's world then
A -> ! or B -> @.

RULES
======

( the starting player can be alone in a level )
( in this case, we want to prevent them from using the action button )
[ action BPlayerOn ] [ APlayerOff ] -> [ BPlayerOn ] [ action APlayerOff ]
[ action BPlayerOn ] -> [ BPlayerOn ]

( restore the action if the player is not alone )
[ action APlayerOff ] [ BPlayerOn ] -> [ APlayerOff ] [ action BPlayerOn ]

( when the player presses 'x', switch paradigms )

[ action APlayerOn ] [ ABlack ] -> [ action APlayerOn ] [ BBlack ]
[ action APlayerOn ] [ AWall ] -> [ action APlayerOn ] [ BFloor ]
[ action APlayerOn ] [ AFloor ] -> [ action APlayerOn ] [ BWall ]
[ action APlayerOn ] [ BPlayerOff ] -> [ APlayerOff ] [ BPlayerOn ]
[ action BPlayerOn ] [ BBlack ] -> [ action BPlayerOn ] [ ABlack ]
[ action BPlayerOn ] [ BWall ] -> [ action BPlayerOn ] [ AFloor ]
[ action BPlayerOn ] [ BFloor ] -> [ action BPlayerOn ] [ AWall ]
[ action BPlayerOn ] [ APlayerOff ] -> [ BPlayerOff ] [ APlayerOn ]

( players can push walls, and inactive players within )
( this group loops endlessly if your first move is to push a wall )
rigid [ > Player | Wall ] -> [ > Player | > Wall ]
+ rigid [ > Player | PlayerOff ] -> [ > Player | > PlayerOff ]

( after walls are moved, ensure either a floor or wall is in every cell )
late [ APlayerOn ] [ Floor Wall ] -> [ APlayerOn ] [ Wall ]
late [ APlayerOn ] [ no Floor no Wall no Black] -> [ APlayerOn ] [ AFloor ]
late [ BPlayerOn ] [ Floor Wall ] -> [ BPlayerOn ] [ Wall ]
late [ BPlayerOn ] [ no Floor no Wall no Black] -> [ BPlayerOn ] [ BFloor ]

( one-way gadget, the three blocks in the middle that must be moved )
( but also demonstrates how difficult it is to stop a player in this )
( variant. My design goal is for purple to have to cross the screen )
( in order to unlock the gadget, but purple seems to be able to unlock it )
( from the right in any case! Moar thinking! )

( in any case this kind of works as a simple level )
( B unlocks A, and then A has to ferry B back across the level )

( Solutions )

(
Currently each color only has to reach a single target so having multiples just gives more options.
The difficulty must then be the same or easier, except for the confusion factor. An option is to
have all players have to reach a target which may make multiple players and targets an option.
Another interesting thing that this level illustrates is how the color imbalance affects the game.
The most powerful player in a zone is the one that can move freely, and it can trivially assist the
other player to cross given a single block to ferry them in.
