How to make a Celeste style precision platformer with AI

Precision starts with a predictable character

Set run speed, jump height, acceleration, and air steering so movement responds consistently. A brief ledge grace period and jump input buffer can make timing forgiving without removing precision. Define whether a dash travels diagonally, pauses gravity, and recharges on landing. Show a trail while it is available and a separate cue once spent, so players can plan a sequence without guessing about hidden state. Smooth animation frames from a sprite sheet generator make each jump state readable. Sound effects on jumps and dashes confirm each input.

Use short rooms to teach through attempts

A screen-sized room can focus on one problem, such as dashing through a narrow passage or landing before a hazard crosses the route. Show the goal early, then place checkpoints before longer sequences and restart quickly after a fall. Optional original collectibles can sit on harder side paths, letting players choose an extra challenge without blocking the main climb. Screen-sized rooms connected into a larger map are the basis of a metroidvania.

Shape a climb from deliberate room challenges

1. Build the first version in 2D

   Choose 2D at creation because a precision platformer depends on clear collision edges and compact side-view spaces. Chatforce cannot switch the game between 2D and 3D afterward. Choose the platformer scaffold and describe one screen-sized room with a starting ledge, a gap, a safe landing, and an exit. Use simple placeholder colors at first so the route is easy to inspect. Give your climber a new identity and goal, such as a botanist ascending a wind-carved tower, with original characters, art, names, music, and story.

2. Describe the movement vocabulary

   State the controls and the intended response: run, jump, steer in midair, and dash in a chosen direction. Explain whether the dash pauses gravity and how landing restores it. Ask for consistent acceleration, a short jump grace window, and buffered jump input if those features suit your design. The AI needs useful boundaries, so describe how far a dash travels and how soon the character can act again. Test across a wide gap and a narrow landing before adding a hazard. Make sure the character's state is visually clear after using the dash.

3. Create rooms that isolate one lesson

   Plan a short sequence in which each room emphasizes a different use of the same controls. One can teach the dash across a gap; another can ask the player to recharge it by touching ground before reaching a higher ledge. Introduce moving hazards only after the static version reads correctly. Keep the goal and likely danger visible within the screen, and place checkpoints where a new chain of moves begins. Ask for a quick restart at the room entrance and a short transition so failed attempts do not interrupt practice.

4. Add a reason to explore off the main route

   Place optional collectibles on routes that ask for extra control, such as a dash through a tight opening followed by a safe landing. Give them an original name and shape, and make their collection persist even if the player later fails before the exit. Add assist ideas through explicit prompt details: slower hazard motion, a more generous dash recharge, or an optional extra air dash. Present these as adjustable ways to explore the climb, not as judgments about skill. Establish a visual contrast between safe platforms, hazards, and interactive surfaces.

Example prompt: Make an original 2D precision platformer about a botanist climbing a wind-carved tower to retrieve a seed archive. Use responsive running, a jump with slight input buffering, and a directional air dash that recharges on landing. Build four screen-sized rooms that teach one idea at a time, with visible hazards, quick room restarts, and checkpoints before longer sequences. Put optional luminous seed tokens on harder side routes. Include adjustable assist options for hazard speed and dash availability. Use original characters, names, art, music, and story with a crisp illustrated look.

Tune control by replaying the same jump

Use one difficult gap as a control test and repeat it after each change. If the character overshoots a narrow landing, adjust air steering or dash duration before changing the platform layout. If a jump fails despite correct timing, check the collision boundary and input buffer. Make the outcome of a dash consistent from attempt to attempt. Invite someone to play without explanation and watch where they expect a recharge or restart. Their assumptions reveal whether your cues match the rules you intended. A clean pixel art style keeps hazards readable at small sizes. One-touch variants of the same idea appear in Geometry Dash-style runners.

Publish a climb people can practice

Once the movement and first rooms feel coherent, publish the game as a browser-playable experience at a shareable URL. Friends can start without an account and tell you whether the controls are understandable or a room needs a clearer cue. Chatforce's AI team builds code, art, and audio, and you can iterate by describing a problem in chat and replaying the adjustment. You own the work, and published games have no watermark. A short opening climb is enough to get useful feedback on movement before you build a much longer ascent. If you are used to building platformers in an editor, the GameMaker alternative page compares that route. An endless runner mode can reuse the same movement in one long level.

Frequently asked questions

Can I make a direct copy of Celeste?

Use it only as a reference for broad precision platformer traits. Make your own game with original names, characters, art, music, and story, along with distinct rooms and movement details.

Can I include dash recharge and quick retries?

Yes. Describe the dash direction, duration, recharge condition, and what happens after a fall. Ask for screen-sized rooms and a fast restart point so players can practice.

Can I add assist options?

Describe the options you want, such as slower hazards or an additional dash. The platformer scaffold gives you a starting point, while specific movement and assist rules belong in your prompt.
