Side Scroller Maker — Describe a Level, Play It
One line about a place becomes a side-scroller you can play — a full route, a double jump, three things to find, and someone who answers.
Walk the route.

One engine, four horizons.
Neta Studio turns the sentence into the whole level — the parallax sky, the walkway, the cast, the pickups and the ending — then publishes it at a link that opens on a phone. The composer above runs Neta’s Game Maker skill, so what comes back is playable, not storyboarded. The four routes below are the same build with four different inputs. Walk the Liyue route.
- A route, not a backdrop. Ground segments, gaps and ledges with real collision. The camera follows, the hero falls if you miss, and a double jump clears what the drawing promises.
- Three pickups and one person. The counter is the goal. A named character on the route gives you a line and two replies; the gate at the end opens at 3/3 and the ending says what you did.
- One build, four worlds. Palette, skyline, props, cast and objective come from the same level data. Change the place and the scene changes; the controls and the physics stay the same.
Questions, answered.
Do I need an engine or a build step?
No. The level runs in the browser from a link. There is no install, no export and no tile editor to learn before the first route exists.
Is this a real platformer or a scrolling background?
A real platformer. Gravity, collision, gaps you can fall into, coyote time, a double jump and a respawn point. The scrolling is the camera following the hero, not a video.
Can I use my own characters and places?
Yes. Describe the place and name the cast; if they already exist in the world, they keep their look. The four routes here use Genshin Impact, Horimiya, Jujutsu Kaisen and The Boys as proof.
What do the three pickups do?
They fill the counter. At 3/3 the gate at the end opens and the ending card records the run; before that the gate stays shut.
Will it work on a phone?
Yes. Left, right and jump sit on screen, and tapping near a character opens the conversation. The same link opens on desktop.
How long is one level?
One route is roughly 4,000 pixels — about two to four minutes if you collect everything. Four routes ship in the demo, and each is a separate level.
Can I change the level after it is made?
Ask for a new route or a change to the same one. The level is data, not a baked image, so the physics and the counter keep working when the layout changes.
Where does the story come from?
From the place and the person you name. Each route has one character with a line and two replies; the ending closes that small loop instead of pretending to be a full campaign.
Start with one route.
One line for the place. The first ledge is down before you finish typing.
