Make a 2D game from a description

A 2D game maker builds games on a flat plane: you see the action from above or from the side, with sprites or simple shapes instead of a full 3D world. Modder makes these by drawing a flat game with a fixed top-down or side camera, so you get crisp shapes, smooth motion and physics without any setup.

By the numbers

A new game on Quick build: ~7 min
A new game on Long build: ~25 min
Games it builds, played in the browser: 2D and 3D
Where the games play, no download: Phone and desktop
Players in one online room, bots in empty seats: Up to 10
Per game, up to 2 MB each: 2,000 files

Build times are the builder's own estimates for a new game; the rest is from Modder's limits on Oct 28, 2026.

Making a 2D game here

Pick the view
Say whether you look down on the action or watch it from the side. Top-down suits arenas, territory and snake games; side-on suits runners, rhythm games and anything with jumping. If you leave it out, the builder picks the one the idea needs.
Let it build and check
The builder writes the game, generates sprites and icons where shapes won't do, and adds sound effects. Then it plays the game in a browser with real input to check that the controls respond, the score counts and the game ends when it should.
Polish by asking
Flat games are all about readability and juice. Ask for a bigger trail, a screen shake on a crash, a combo counter, a brighter palette. Each change is saved as a version you can roll back to.

How 2D works on Modder, honestly

Modder has one engine for every game, built on three.js, and a 2D game is that engine with a flat camera. That's good news for physics, lighting effects and smooth scaling to any screen size, and it's why the .io games here hold dozens of bots at a steady frame rate.

It's less suited to classic pixel-art platformers built from hand-placed tiles. If you want a tile editor, frame-by-frame sprite animation and pixel-perfect collision, a dedicated 2D engine like GDevelop, Construct or Godot will serve you better, and our guide on how to make a video game covers them. If you want a fun flat game made for you in minutes, start here.

What it does well, and what it doesn't

Good at

.io arenas with lots of bots, territory and snake games.
Arcade games: dodgers, slicers, one-button and rhythm games.
Board-like and puzzle games where the whole game fits on one screen.

Current limits

Not a pixel-art tile editor: hand-placed tile levels and frame-by-frame animation aren't its strength.
Long platformer campaigns come out short; a handful of levels is realistic.
Made for keyboard and mouse first; touch is a fallback.

Questions

Can I make a pixel-art game?

You can ask for a pixel-art look and the builder will generate art in that style, but there's no tile editor. For a hand-built pixel platformer, a dedicated 2D engine is a better fit.
