All 21 worlds

Rev Rush: Pixel Moto Runner

Rev Rush is one continuous ride, not a menu of levels. The world changes every 12,000 units of distance — roughly 39 seconds at the start and about 20 at top speed — and it changes without a cut: the sky, the ground, the weather and the music cross-fade while you keep riding. After the twenty-first world the cycle starts again from the first, so the ride has no end and no loading screen.

Every world brings three things of its own: its weather, its music and one moving hazard that exists nowhere else. That last one is the reason the twentieth world does not feel like the fifth.

What the worlds look like

Nineteen of the 21 worlds, one frame each, taken from screen recordings of the game on iPhone, with the score bar and buttons cropped away. Sky High (14) and Forest (16) are not here yet. In some of the recordings the bike had been repainted in the garage, which is why it is not always red.

Six ways a hazard can move

The twenty-one signature hazards are not twenty-one unrelated ideas. They are six kinds of movement, each asking a different question of the same single tap:

Wave — a front that travels along the ground toward you. Jump when the edge arrives, not where it stands.
From behind — something steps out of the background silhouette into the lane. What was scenery is now an obstacle.
Boomerang — it passes, turns, and comes back. Do not write off what has already gone by.
Split — one object becomes three in mid-air. One answer turns into three.
Aimed — it aims at you. Do not commit too early.
Chain — a connected run with exactly one gap. Not "jump" or "don't jump", but "be in precisely that place".

Each family appears three or four times, and worlds that share one are kept far apart: the wave runs in worlds 5, 7, 13 and 20, and something steps out of the background in 6, 10 and 16. You meet the same verb again only long after you have stopped expecting it.

What every world also has

Beyond the signature hazard, each world carries its own sky in bands, its own silhouettes, its own ground texture, its own weather in two layers — one far, one near — and its own soundtrack. There are 21 pieces of music, one per world, and they cross-fade at the border rather than cutting.

Four of these worlds — Sea, Underwater, Castle and Space — are the ones you ride through on the front page of this site. They are not drawings of the game: the page runs the game's own drawing code on the game's own data. That is explained on How it's made.
