Die fast. Try again even faster. Scream a little.

Meet Doppler, a tiny blue ball of nerves with a red bandana fluttering in the wind.

Welcome to a brutal, lightning-fast platformer built for speed, precision, and chained retries. Every level is a test of timing and mastery.

A diamond awaits in every level.
Only perfect runs will earn you an S-rank.
It’s up to you to find the fastest path… your best-time ghost will follow you on every attempt.

Tight controls, instant respawns, and punishing stages await.
You will fail. You will improve.
And one day, you will hit that perfect run.

No excuses.
No mercy.
Just you, Doppler… and speed.
