Heyo! I'm Magdi Hazaa, the creator of this game. Thanks so much for visiting Cosmic Chat. This was a personal project that took me close to 4 months to finish. I built it using a WebGL library; Pixi.js, with Node and Socket.IO for the back-end. And I painted the assets using a combination of Photoshop and Illustrator, with After Effects to animate some of the sprites.
If you're curious, here's the GitHub repository for this project
