Hey, I just wanted to check before I'm putting a lot of effort into the challenge. I want to build a layer upon Github's Gist interface by using a Chrome extension. I'm not sure if you accept a web browser extension as a web-based game. More details here
Thanks in advance!
Sounds interesting! Chrome extensions are fine. Please just be sure to make a note of it the README along with any additional setup / configuration required.
