The first round of testing has begun, so for the next couple weeks I'll be getting feedback and making changes based on that. For everyone who volunteered to test but haven't heard anything - stay tuned, I'll be sending more invites once I get more content pushed to the server.
As an aside, I made a post to Gamasutra that gives a little insight into the dev process, the reason it can take longer than expected, and why that's ok: Best Day of Game Dev, Ever
