🔴 Laser Maze

How to play

You start as a blue dot in the bottom-left corner of a dark grid, with a green door in the top-right. Between them are red laser beams. Walk to the door without touching one and the level goes up, generating a busier layout at once. The clock keeps running throughout, so this is a race rather than a puzzle to take slowly.

• W A S D or the arrow keys — move at 3 pixels per frame. Arrow key scrolling is suppressed, so the page stays put.
• Start button — begins a run, resets the level to 1 and starts the clock. It reads Restart during play.

Scoring

There is no point score. The two figures are the level reached and the elapsed time in tenths of a second, which starts at Start and never resets between levels. Each level generates 3 plus 2 per level beams, so level 1 has 5 and level 4 has 11. Touching a beam costs no life and does not reset the clock — you are simply put back in the starting corner. Only Restart ends a run.

Tips

• The horizontal beams slide up and down; the vertical ones are drawn in a fixed position and never move. Treat the verticals as walls to route around.
• Beams are placed at random, so some layouts are far kinder than others. A hit only costs position, so take the crossing rather than waiting.
• Wait beside a moving beam and cross just after it passes rather than trying to outrun it.
• Holding two keys moves you diagonally and covers ground faster, which helps when a gap opens briefly.
