This is the start of a challenge to get a pull request out every day for the next 24 days (every day until Christmas).
My first pull request was to Thrust, a pacifist bullethell game created in Unity3D. The request that I made wasn't very large, in fact it consisted in only a few tweaks to the README.md file.
I added a new section to the file that gave users a link to a playable build of the game for in-browser play (hosted via Github.IO). I also changed the formatting of the file so different sections would markdown header tags rather than just have plaintext with colons after to designate sections.
Here's a link to the pull request I made for Thrust. Thrust/pull/#1
