v0.9 · open source

Sketch a game today, ship it this week.

A small 2D engine with a readable API, hot reload and a scene editor that stays out of your way. Runs on desktop and the web from the same project file.

↻

Hot reload

Save a script and the running scene picks it up without losing state.

◇

One project, two targets

Desktop and WASM builds from the same scene and asset files.

⌗

Readable API

No inheritance towers. Actors, components and a fixed 60 Hz step.

4    override void Update(float dt) {
5      // grid-aligned movement
6      var dir = Input.Axis("move");
7      Body.Velocity = dir * speed * dt;
8    }
9  }

note

Velocity is in pixels per second. Multiply by dt or your game will run at monitor speed.
