A couple notes on the LIES entities:
As noted before, movement SPEED (the fifth argument) affects what type the LIES are. Movement TYPE (the fourth argument) seems to do nothing.
Speed 0 summons a spawner that functions as in the main game, spouting out LIES to the right (same way as entity movement type 4, it will move right until it goes offscreen and if it hits a wall, it stops) at regular intervals at what looks to be speed 6 (slightly faster than Viridian).
Speed 1 summons a single LIES entity at the coordinates given, which functions as one made by the spawner. It does NOT make multiple "LIES" without a spawner i.e. "Chinese Rooms"/"Spikes Do!" in the main game, I think you need an offscreen spawner for that.
Speed 2 makes a projector that I *think* removes LIES touching it but is otherwise unmoving NOPE IT DOES LITERALLY NOTHING WOOO.
The projector does actually do something, it kills the player on touch
In addition to that, in (18,11) (Chipper Cipher in the main game) LIES disappear when they reach x position ~264, so the place where the projector sits at in the main game.
Exactly the same thing happens with The Solution Is Dilution clouds, they have fixed speed (its -5 i think) and direction (13), 4th argument will do nothing and 5th argument controls variant (0 for spawner, 1 for cloud, 2 for top) Each of these functions exactly like LIES do, and in (14,9) (Level Complete! in the main game) clouds will disappear after they reach y position ~56.
An invalid speed number in these rooms, so anything else than 0, 1 or 2, will create the normal purple box enemy that will move with the given direction and given speed.
