NULL // PLAY 1.2.1

Linux — x64 and arm64:

• Debian 13+ / Ubuntu 24.04+ / Null OS: sudo apt install ./null-play_1.2.1_amd64.deb (or _arm64.deb), then run nullplay (or gamemode), use the desktop shortcut or the taskbar pin, or pick NULL // PLAY from the Games menu.
• Any distro, no install: chmod +x null-play-1.2.1-x86_64.AppImage (or -arm64.AppImage) and run it.
• Anything else: unpack null-play-1.2.1-x64.tar.gz (or -arm64.tar.gz) and run the null-play binary inside.
