How to Play

  • You are a glowing point descending a neon loss-landscape. Steer with the arrow keys, A / D, the mouse, or by dragging on touch.
  • Thread the gap in each pink gradient wall and scoop up the green minima — chaining them builds a combo multiplier (up to x12).
  • Dodge the spinning yellow saddle spikes. Grab a cyan shield when it drifts past — it eats one hit. Three lives, then you converge.

What Makes It Tick

Everything is delta-time driven, so it runs the same on a 60Hz laptop or a 144Hz monitor. Difficulty is a moving target: scroll speed and spawn rate climb with your score and the seconds survived, the wall gaps tighten each level, and a 220-particle pool keeps the explosions cheap. Your high score lives in this browser, so beating it actually means something. Hand-built by Opus 4.8 — no auto-generation, every line on purpose.

Mastering the Gradient

As you drift through the vibrant neon abyss, your primary focus should be on the combo multiplier. Each green minimum you collect builds your score and streak, with the potential to rise to a hefty x12 multiplier. But remember, threading the needle through those pink gradient walls is no cakewalk—precision and timing are your best friends.

Here's a pro tip: try to anticipate wall movements. The walls can shift and tighten, so plan your path a few steps ahead. It’s not just about dodging—it's about predicting where the openings will be. Keeping an eye on the spawn rate and wall arrangement can turn you from a novice into a gradient master.

Power-ups and Pitfalls

Power-ups are your lifelines. The cyan shield doesn’t just absorb damage; it gives you the confidence to charge through tricky sections without fear. Timing your grab of the shield is crucial—missing it might mean the difference between a high score and a quick exit.

On the flip side, those spinning yellow saddle spikes are relentless. They appear unexpectedly, and a single grazed hit counts against your lives. Stay sharp and agile; a quick tap on the arrow keys can mean the difference between survival and a crash landing.

FAQ

It is the algorithm that trains most neural nets: keep stepping toward the lowest point of a landscape. Here YOU are the point, the walls are the landscape, and the minima are literally worth points.

Yes, in this browser via localStorage. Clear your site data and it resets. There is no server leaderboard — it is just you versus past-you.

Keyboard for precision, mouse or drag for flow. Mouse steering eases toward the cursor, so flick-and-settle works well for threading tight gaps.

Focus on timing your movements and predicting wall gaps ahead of time. Collecting multiple green minima in succession builds your combo multiplier, so aim to thread through walls efficiently.
