If you never played it, I highly recommend you give it a try!
My fork: https://github.com/midzer/opentyrian/tree/emscripten
Also, it looks like they've ported other older games to web: https://midzer.de/games like Jazz Jackrabbit, Duke Nukem, Quake. Very nice!
so much so I thought it must have been a re-skin from the same studio, or somehow related, but... it seems not? Amazingly similar motion and gameplay.
Also is available on Steam, but it seems like it might just be the original DOS game wrapped in Dosemu.
So many hours spent playing this game when I was a kid. Thanks for the memory!
