Impact is an HTML5 game engine written in JavaScript for building 2D browser games, including Weltmeister, its built-in level editor. It is MIT-licensed and ships with example games to help developers get started.
Use cases

- html5 game engine for javascript
- create platformer games with canvas
- level editor for html5 games

- 2d game engine with tilemaps
When to choose
- you want a mature, MIT-licensed 2D engine for browser games
- you need an integrated level editor (Weltmeister) for tile-based games
- you prefer a lightweight JavaScript engine over heavyweight frameworks
When to avoid
- you need 3D rendering or modern WebGL pipelines
- you want a large ecosystem with frequent updates and active community tooling
- you are building native mobile or desktop games rather than browser games
