GLESGAE was an engine I started specifically to learn OpenGL ES, OpenGLSL ES and to fiddle with Android and component systems. It didn’t really get anywhere much, but the full source can be found on GitHub if you’re curious.
When Arcade Badgers started, the plan was to build on it into the main engine for it’s commercial endevours, and another project was started alongside it; JESSIE. This was when it was rewritten from C++ to straight C.
I haven’t touched it in a while. It compiled last time I looked though!
