I've been working on a web-based multiplayer game that allows the player to act as a Head Coach of a college football team.

I started working on this in my free time in 2010 or 2011, and initially used it as a project to learn databases, cloud, et cetera. I never actually set out to be a game developer!

So this is my first attempt at game design, and has its share of issues, but I'm proud of it.
