About MOMENT
MOMENT is a small, free browser game built around one unusual idea: the world only moves when you do.
Most games race against a clock. MOMENT removes the clock entirely and hands it to you: time advances only when your cursor moves, and fast motions push danger farther. Because the world waits for you, a run depends less on reflexes and more on reading the screen and committing to a route. Runs are short and the next attempt starts instantly, which is exactly the loop I wanted.
The game runs entirely in your browser. There's nothing to install, no account to create, and it works the same on a laptop or a phone.
Its two main challenge modes are One Life, an open-ended run where one mistake ends the attempt, and Daily Challenge, a shared eight-stage course that starts hard and gets tighter at every stage. Verified One Life results can be published to an optional global board ranked only by levels cleared, with equal levels sharing equal rank. Endless Practice is the training mode for learning hazards and routes without losing the whole run.
How it was made
MOMENT is a single, self-contained web page rendered on an HTML5 canvas. The core mechanic, tying the flow of time to the distance your cursor moves, takes one sentence to explain but keeps producing situations I never planned for. I'm still tuning the difficulty, adding hazard types, and polishing the feel.
Under the hood, everything is deterministic: the same seed always produces the same course, bullet for bullet. That one property quietly powers most of the site's features. Shareable course links, the fixed Daily layout, and the server-side replay verification behind the ranked board all fall out of it.
What the game tries to be
A few rules have survived every update so far:
- Always telegraphed. Every hazard announces itself before it can hurt you. A death should feel like your decision, never an ambush.
- Determinism is sacred. No hidden randomness during play. If two players make the same movements on the same course, the same things happen.
- Light by default. No installs, no accounts, no pop-ups asking for things. The page loads, and you play.
