Black Diamond

About

Black Diamond is a simple arcade title hidden inside the TempleOS operating system. You control a diamond shape that moves around the screen while collecting smaller gems to grow larger. The game gets harder as your score rises because obstacles appear faster and your movements become more restricted. It runs entirely in single player mode with no multiplayer options or complex menus to navigate through. This project comes from Terry A. Davis, who built TempleOS as a personal operating system for religious and creative expression. Since it is an embedded feature rather than a standalone release, the code reflects a very specific era of indie development history. Community members who dig into niche systems often rate these hidden features highly just because they are so rare to find in modern software. The graphics stay basic throughout the run, but the difficulty curve keeps things engaging for anyone looking for a quick challenge.
