FLUX
Collect every star before the clock runs out.
A platformer about crossing a room fast: grappling hook, portal gun, dash and double jump.
Runs in your browser. Nothing to install.
The full version adds the map editor. Build a level, send the link, and anyone can play it in their browser without owning the game.
GRAPPLING HOOK
Fire at anything solid and get pulled to it. Release, swing, fire again. Chained swings cross a gap nothing else reaches.
PORTAL GUN
Two ends, either direction, momentum preserved. Put one underfoot and one overhead and the fall never lands.
DASH
A flat burst of speed that clears a pit no jump can. On some of them it is the only way over.
DOUBLE JUMP
A second jump in mid-air. Run off a ledge without spending the first and you keep both.
A ROOM AND A CLOCK
Every level is a room full of stars and a clock. Reaching them is the easy part; reaching them in time is not, and the route you take is yours to work out. Electric arcs kill on contact, so speed and care pull in opposite directions. Comes with a hand-built level, a tutorial that teaches each ability by making you use it, and endless randomised rounds.
BUILD YOUR OWN FULL VERSION
The map editor ships inside the game itself, not a separate tool and not a web page. Paint a room, scatter stars, hang hazards, set the rules, then play it without leaving the editor and keep editing. The editor is part of the full version; the browser demo is for playing.
SET THE RULES
A map carries its own physics and its own clock, and they travel inside the link, so it plays for whoever opens it exactly the way you tuned it.
- Grant or withhold each ability: a hook-only room, a no-portal room, or nothing but your legs
- A clock from ten seconds to five minutes
- Gravity from a quarter of standard to three times it, a floaty drift or a dead weight
- Top speed, acceleration, ground friction and jump strength, each on its own slider
EVERY MAP IS A SHAREABLE LINK
A level is compressed into the URL itself. No upload, no account, nothing hosted. Send someone the link and it opens straight into your map in their browser, with nothing to install. A full level runs a few hundred characters, well inside what a URL will carry.
- Paint walls, spawn, stars, lights and hazards
- Test-play in place, then keep editing
- Copy a
#m=…link and send it
What stays fixed is how the hook and the portal gun themselves behave. Those are the same in every map, so what you learn in one still applies in the next.
