THE HARMONIC ODYSSEY DEMO So, what's the ultimate proof of concept for a game..? A working demo! Initially published utilizing what became a highly customized rpg maker mv engine, I realized I wanted to take the final game further, and have begun the process of porting everything over to Unity. Even so, the experience of seeing a demo through to completion (using only javascript to code, no less!) was invaluable experience in understanding how to work as a solo and small-team developer. want to give it a try?
