A small demo 2D video game running in a web browser powered by WebAssembly.

![Breadcrumb Lost](breadcrumb-lost_preview.gif)

*Disclaimer*: This was never intented to be a real game. The purpose is to demonstrate programming games from scratch in AssemblyScript.

- [Control of the game rendering loop within Wasm](https://github.com/ttulka/2d-videogame-in-assemblyscript/tree/requestAnimationFrame) ([blog post](https://blog.ttulka.com/animation-in-canvas-with-webassembly))

- [Automatic inlining of image assets](https://github.com/ttulka/2d-videogame-in-assemblyscript/tree/inliner)
