TempleOS (included games)

TempleOS, creation of Terry A. Davis, is a custom, ring-0 operating system written in a programming language called HolyC (a cross between C and C++). The operating system has gone through multiple different names (J Operating System, SparrowOS, and LoseThos) until it became TempleOS. The operating system's development ended in 2017 after the tragic passing of its creator.

TempleOS does support sound, through the use of Pulse Audio and early DOS-like system beeps that very in tone.

TempleOS comes with multiple different programming demos, documentation, utilities, and games that are not found outside of the Operating System installation. The games are, in general, unique variations of classic games, such as SkiFree, Flappy Bird, Castle Wolfenstein, Battlezone, and more. The games include:

• Titanium - A vertical scrolling arcade shooter like 1942. The goal is to shoot as many enemies as you can. There is no time limit and nothing shoots back at you.
• Black Diamond - A downhill skiing arcade game like SkiFree. The goal is to make it to the bottom of the slope while dodging trees, rocks and wild dogs.
• Flap Bat - A horizontal scrolling arcade game like Flappy Bird. The goal is to eat the bugs until you get to 100%. There are no obstacles nor any enemies to worry about.
• Varoom - An arcade racing game. The goal is to make it around the track as fast as possible while trying to stay on the track.
