A while back, the "Pong Wars" Day vs. Night visualizer made the rounds here. I loved the concept of the two colors battling for territory, but I wanted to see if I could evolve it from a passive simulation into an actual competitive experience.
I forked the original project and built Pong Wars Reloaded. I intentionally avoided frameworks and game engines to stay true to the original, it's just pure Vanilla JS and HTML5 Canvas.
The project is free and open-source. Feedback welcome. Try to beat the AI (hint: it's not too hard yet)!
