The Game

Different games.
Same consequences.

0:00

Move. Collect sparks.

The 6-second clock starts. Nothing can hurt you yet. Everything you do is being recorded.

0:06

Meet yourself.

Your exact path becomes an enemy, replaying forever at your speed. You get 0.6 seconds of warning. Touch it and it's over.

0:12

Repeat.

Every six seconds adds another you. Seven by the end. None of them chase you. They follow your old plan.

Standing still loses.

Your own echo will be waiting on that exact spot. Keep moving. Sparks give you score and a combo, and a reason to leave.
