Hello, Subject

You move things with your mind. That is all you have. Find the exit.

The Facility runs a psychokinetic assessment programme. Two hundred chambers, one exit each, and a Subject  (you)  with no tools, no weapons, and no way out except through.

Drag a cube through the air. Stack two. Throw one hard enough to shatter glass. Slide a mirror into a laser and the beam turns ninety degrees. Rest a weight on a pressure plate and a blast door opens somewhere you cannot see. Lift a sentinel off the floor and it cannot aim at you.

Every chamber is one idea, taught and then finished. Learn the thing, use it, move on.

Build your own

The full editor ships with the game. Every tile, every mechanism the campaign's chambers are made of (lasers, mirrors, plates, doors, turrets, sweepers, dispensers, moving platforms) is yours to place.

• Unlimited chambers. Draw the room, wire the mechanisms, write the opening line, play it instantly.
• Group them into structures and play them one after another, like a campaign of your own.
• Share with a QR code. One code carries a whole structure. Another player scans it and it lands in their game, on desktop, iPhone or Android, the code is the same everywhere. No account, no server, no upload.

Inside

• 200+ puzzle chambers. No generators, no filler. Each one a mechanism you have not met yet.
• Physics you can feel. Cubes, mirrors, lasers, sentinels, moving platforms, acid, fragile floors, pressure plates.
• Fun with Portals. A bonus set of 10 chambers where the rules change.
• A level editor with no limits, and share codes that cross platforms.
• Keyboard and mouse. Arrows or A/D to move, Space to jump, drag with the mouse to lift. That's the whole control scheme.
• Also on mobile. Hello, Subject is out on iOS and Android: same chambers, same editor, touch controls: stick on the left, tap right to jump, drag to lift.
• Native and small. Around 10 MB of game, 11 MB of music. No launcher, no account, no network.
