Cool (and intense!) game :) Pretty impressive you had something like that running on a PDA 20 years ago, I was probably playing J2ME games on a Sony Ericsson at that point so don't know the performance of those.

This constraint + your solution was pretty interesting:

I'd bet on that in 20 years TypeScript will no longer be maintained and also no longer be the most popular transpilation source language for JavaScript. Seems the JavaScript ecosystem always eventually finds a new "source" language even though everyone at the time is certain it won't happen with this current one.

Probably still wouldn't be hard to get the game running though, will still be easy to install old TypeScript compiler and run it.
