Colors Of V

Light is the mechanic, not the lightingA black vector screen and three gels in the printer's colours. Yellow blocks blue, magenta blocksgreen, cyan blocks red — real subtractive optics, so they stack. Yellow and cyan together leavegreen and nothing else. Three gels, seven usable states, and every one of them is a differentroom. What you cannot see cannot see youInvisible is not hidden. It is absent. A wall you cannot see is not solid and you walk straightthrough it. A trap you cannot see cannot cut you. An enemy you cannot see is frozen — and cannotbe shot. Visibility and collision are the same channel, so they can never disagree with eachother, and every gel swap rewrites the floor plan under your feet. Stacking costs lightEach gel darkens the tube and tightens what you can see. Seeing one thing clearly means seeingless of everything. And you cannot flip a wall into your own body — the swap is refused ratherthan shoved through, which makes timing a gel a positional decision, not a panic button. All three gels is total darknessNothing passes, so nothing exists: nothing is solid, nothing can shoot you, and you can shoot nothing at all. It is not a refuge, though — the tube was never built to be held shut. After a couple of seconds the dark starts taking hull, and at four and a half a gel pops off on its own, never one that would drop a wall inside you. Coming back into the light, both sides are blind: you get a second of grace, they stand still for slightly longer. Earn it with a real stretch of blindness; flickering the gels will not farm it. Running is not a planEnemies are faster than you. The only defence is to stop something existing — which is also theonly way to stop being able to kill it. A room does not wake at full speed either: enemies holdfor a moment and wind up, dim while dormant, so you get a room to read instead of a memory test. A hundred levels, ten tiers, one seedNine rooms and a boss, ten times over. The first three are hand-built because they teach thethree rules and nothing generated teaches as cleanly. Everything after is generated from thelevel number, so level 34 is always the same level 34 — a run can be replayed, compared andargued about. Each tier decides what a level is allowed to use, so the campaign teaches in order:primaries, then secondaries only a two-gel stack erases, then walls no light gets past, thendensity on top of all of it.
