Runner is a free, independent, downloadable game made by Jonathan Holmes (sprite art), Ashley Davis (other art), and myself (design, programming). It was finished over the weekend (barring any huge bugs or problems), and is now available for download. You'll need Windows to play it, though.
You can get the game here (make sure to extract the RAR files into the same folder), and get the source code here if you inexplicably get the desire to clean up the code and make the game less of a ludicrous resource hog.
Please feel free to post any bug finds in the comments below, or by emailing me at reverendanthony [a t]gmail [d ot]com.
In about a week, I'll write up a postmortem/apology/explanation for the game. Until then, I'm going to try really hard to not comment on anything beyond bug reports or what have you.
