Tyrian's what gave me inspiration to create a space shooter on mobile! Some of the special weapons in my game are direct inspiration like the Plasma Storm and Soul of Zinglon. Granted my space shooter game isn't a scrolling space shooter though, someday I will try my shot at making one.

Also, it looks like they've ported other older games to web: https://midzer.de/games like Jazz Jackrabbit, Duke Nukem, Quake. Very nice!
