Void Dodger

Void Dodger is a pure reflex action game: you pilot a small ship through a field of asteroids that keeps getting denser, faster and less forgiving. There is no shooting, no upgrade tree and no mercy — just you, an increasing storm of rock, and a survival timer that doubles as your score. The design idea is almost meditative in its simplicity: stay alive as long as possible, and feel your own reaction time improve run after run.

The controls are intentionally frictionless. On desktop, the ship follows your mouse or the arrow keys; on mobile, you drag anywhere on the screen and the ship follows your finger with slight smoothing — which keeps the motion fluid without the ship ever feeling like it is fighting you. Asteroids drift in from every edge with slow rotation and varied sizes, and near misses are tracked as a bonus, rewarding brave flying through gaps a sensible pilot would never attempt. Every asteroid that scrapes past you without contact nudges your score multiplier, so the high-score chase is really about how close to the fire you are willing to fly.

The difficulty curve is where Void Dodger reveals its depth. The first twenty seconds are calm — almost boring, deliberately so. Then the spawn rate climbs, drifting hazards start to overlap flight paths, and by the two-minute mark you are threading genuine needle gaps. Runs end in a heartbeat, and the instant restart keeps the loop tight. It is one of the harder games on the site; the Hard to Master tag is there for a reason.

As an AI-generated game, Void Dodger is our clearest example of prompt-driven difficulty engineering. The whole game was built by Claude, and its spawn ramp is governed by constants exposed in one difficulty block at the top of the file. We ran our difficulty audit prompt on it, played dozens of runs, and tuned the ramp to hit the curve we wanted. The full process — and the numbers we changed — is documented in the prompt library.
