How to Play: GOAL: collect every data chip on the board, step onto the socket to open it, then reach the exit before TIME reaches zero.

CONTROLS

• Desktop: arrow keys or WASD. You can also click and drag toward where you want to go.
• Mobile: swipe or drag in the direction you want to move. Pinch to zoom.
• P pauses, R restarts the level, and any key clears the level card.

WATCH OUT

• Water and fire are fatal unless you are carrying the matching boots.
• Ice slides you until you hit a wall. Force floors push you along their arrows.
• Push a block into water to build a bridge over it.
• Coloured doors need the matching key. Bombs destroy whatever steps on them.
• Monsters walk fixed patrol routes - wait for the gap, then cross.

SCORING left on the clock. Beat your best time to raise your total on the leaderboard.

• Each cleared level is worth its number x 500, plus 10 points for every second

MICROGIC 89 is a retro tile puzzle set inside a 1980s microchip. You play BYTE, a courier who has to collect every data chip on the board, unlock the socket they open, and reach the exit before the timer runs out.

27 hand-built levels, each one testing a different machine: sliding ice floors, force belts, teleport pads, cloning machines, trap doors, live bombs and patrolling bugs. Nothing on the board is decoration - if a gadget is there, you have to use it.

Every level you clear and every second left on the clock feeds your score, and the global leaderboard remembers who runs the chip best. Play it flat in the classic top-down view or flip to 3D at any time. A full level editor is built in, so you can draw your own maps and play the ones other players have published.
