How Long Can You Last? drops a tiny swimmer into a microscopic survival arena crowded with threats. Viruses, needles and rival swimmers all want you gone, and a single hit ends the run.
Movement is your armor: dash through tight gaps, build energy from near misses, and slow time when the screen gets too hectic. Every run is a fresh attempt at your personal best, and tongue-in-cheek achievements give you extra reasons to come back.
The game is free to play in the browser with no installation or login. Best scores and achievements are stored locally in your browser, and the interface ships in English and Simplified Chinese.
How to Play
Steer the swimmer around the arena and dodge everything — viruses, needles and rivals. Grazing danger builds energy you can spend on time-slowing, so the safest run is also the most resourceful one. One hit ends the run; after that, retry immediately and chase your best survival time.

Tips & Tricks
Near misses charge your energy — skimming threats beats avoiding them entirely.
Save slow time for the moments when several threats converge at once.
Precision movement (Shift) is your friend in tight needle gaps.
Don't dash into unknown clutter; a dash you can't steer is a death sentence.
Achievements are local to your browser, so your streaks stay yours.
