Hello, Cog
2026-08-22
The first light. A single COG dropped loose in the basefolder overrides the one inside the stock GOB, and its Print() comes back out to the test harness.

Box Room
2026-08-22
The smallest level this engine will accept: one sector, six surfaces, a spawn point. The floor grid is deliberately loud so that every later experiment can see itself.

Adjoin Gate

Two sectors and the hole between them. Adjoins are how every JK level is more than one room, so this one builds the pair by hand and then walks through it — with a walled-off negative control.

True Colour
