Description

Puzzle selection artwork for the ⊥IW.giga round. In descending order: ⊥IW.giga, ⊥IW.kilo, ⊥IW.milli.

On the round page, the first subround, ⊥IW.giga, is situated in space, with each puzzle appearing as an asteroid. The second round, ⊥IW.kilo, is situated in a planet, with each puzzle appearing as an island. The third round, ⊥IW.milli, is situated on a circuitboard, with each puzzle appearing as a circuit. Once the second subround is unlocked, navigation between the subrounds is possible via a magnifying glass that can zoom in and out.

In the projection device, ⊥IW.giga appears as a series of space rocks and air-locked chambers, with puzzle givers being aliens. The ⊥IW.kilo round took place in a normal classroom setting, with puzzle givers being clean room technicians. The ⊥IW.milli round took place on a circuit board with puzzle givers being robots.

Navigation Puzzle

The navigation puzzle in the projection device involved a multi-state maze. Upon solving some puzzles, devices that allowed for changing the size of the player character unlocked. Many actions, such as going through certain tunnels, using size-changing devices, and getting puzzles from NPC's, required players to be in a certain size.
