Gridflip

GRIDFLIP

Use the arrow keys to move.

When you walk on a tile, it switches color.

Flip all tiles to one side.

The thing at the top is a timer. Whenever all tiles are at one side, the game resets and the timer starts again, but lower. If your timer runs out, it's game over.

Work to get the world record, or your personal highscore. 

There are more colours of tiles introduced every 3 levels, and new ones accessible every 4.

Press C to not be timed, but the world record becomes unachievable.
