It's like an FPS Hotline Miami. It's also been updated loads since I first played it on Windows - tried the Linux build last night and was impressed with how far it has come. Thanks!
I bought a new PC last year (replacing my 2009 desktop) and switched from Windows to Linux Mint as my main OS. I dual boot with Win10 just for when I need a few pieces of software that don't run in Linux, but now always favour Linux versions. Anger Foot is the first graphically intensive game I've played on my new PC (3060 Ti) - up until now I have just been playing a UFO/X-COM TFTD mod, so it's good to give it a chance to run hotter! It's fun playing this new version, with different levels, baddies and unlockables from what I remember.
