Electric Rogue

Electric Rogue is a minimal first-person with graphics and an abstract cyberpunk theme. It was well-received thanks to its unique visuals and intuitive, familiar gameplay that reinterprets old concepts in a new way. But most importantly for me, it's the first complete game built on what I call the NoTime Engine, an old dream of mine.
