Thanks.

The current method of building a game is the same as the walkthrough for building an app[1], except you make a custom view and override its draw method. For higher performance, you can create an OffscreenCanvas and draw into it however you want. There's no API to wrap WebGL2 more conveniently than this yet.

I definitely should and will wirte a guide that takes you from nothing to a full fledged game. But right now, the guides are all geared towards making apps, since before we can make games, we need to make gamemaker tools, like spritemakers and mapmakers.
