-In 2010 Doug McInnes [made](https://github.com/dmcinnes/HTML5-Asteroids) [this cool JavaScript+HTML5 Asteroids clone](http://www.dougmcinnes.com/2010/05/12/html-5-asteroids).

 ## Asteroids
 
-Asteroids is one of my favorite video games. The day care I grew up in (!) had an original tabletop Asteroids game for the munchkins to play with, so I spent hours on that thing instead of playing sportsball or getting vitamin D. It's super cool in both its simplicity, and its use of vector graphics—as in, the original CRT didn't just do the horizontal scan thing; the tube traced out the vector pattern on the screen, resulting in things like small shapes showing up brighter.

-So I have spent random minutes playing [Doug McInnes's JS asteroids clone](https://github.com/dmcinnes/HTML5-Asteroids) to reset my brain, for years since he first published it back in 2010.

 ## TypeScriptification
 
-I wanted to play with ML reinforcement learning (more on that later), which requires me first to do some code refactoring on the game. Notably, to do training I want to be able to programmatically:

+training I want to be able to programmatically:
 
 1. Reset the game,
 2. Single-step the game loop,
 3. Seed the RNG,
 4. Extract internal state for observation, and
-5. Decouple UI from business logic, so we can run the game logic without a full browser (for both simplicity and speed).

 ## ML reinforcement learning
 
-**This is still a TODO and will get another post if I manage to operationalize anything.**

-My weird idea is to replace the game's demo screen with a live machine-operated game, maybe operated by [TensorFlow.js](https://www.tensorflow.org/js). There has already [been extensive research in training robots to play Asteroids](https://www.gymlibrary.dev/environments/atari/asteroids/); what I'll try to do differently here is specifically train on this browser-playable game.
