Maybe someone in @mastoblind remembers SuperLiam? A game developed in 2004 by Liam Erven (l-works) L stands for Liam.
Well, the game is still on https://l-works.net free both on Mac and Windows, no idea if it works in a Windows virtual machine on Linux systems.
I am playing this with pleasure, but my reflexes are less than 20 years ago, I'm not so quick in shooting and get often wounded severely by strongest/quickest enemies!
