I played Spiral Knights when it first came out. As soon as the game was getting started, I joined. I made it past Tier 2 and was working on getting 3/4 star items, then decided to take a break. It's been a long while since I've played. I downloaded Steam, and started playing it again for a little while.
I used to be able to log-in through facebook on the main site, and play the game when it launched. But, my previously-existing account and the Steam account didn't register as the same, so I couldn't get achievements based off of this one character (the reason I got Steam).
