Logic System

What’s the draw?

Logic System is a 3D puzzle adventure by Erik Tilleby, published under Tilleby on itch.io. You play Origo, a maintenance droid inside a machine whose circuits have stopped behaving. The paths are electronic components, moving conductors carry you between sections, and each service order gives you another repair to work out.

Beta 0.1 was announced on September 24, 2026, with further update posts on September 25 and 26. Tilleby's public profile describes a background in software, games and music, including work under the demoscene name Marillion. The game sits alongside the developer's browser music-management project Backstage Disaster.

The opening circuit makes traversal part of the puzzle. You need to reach the moving parts before you can do anything useful with them. We crossed onto a conductor and rode it between sections of the board, with the glowing power route visible beneath the machinery. This is a beta worth approaching as an unfolding puzzle, with time to read the briefing and learn the controls.

Before you jump in

Controls

WASD moves Origo. Space locks, E carries and P pauses. Follow the service-order briefing for the current circuit.

Devices

Desktop Chrome: opening service order, movement, moving conductors, pause and Continue checked. Later levels and phone play have not been tested.

Our check

September 29, 2026 · Desktop Chrome

We started the first service order in desktop Chrome, moved Origo around the circuit and rode a moving conductor between sections. Pause and resume worked. After reloading the page, Continue reopened the same service order with our position preserved.

We did not finish that circuit or play later levels. This was a representative opening session, not a completed campaign. The notes above describe the movement and machinery we saw; they do not claim that we verified every repair mechanic or later puzzle.
