Now it's public! I recommend playing with a friend since I am a relatively small scratcher, so you will be unlikely to find an opponent naturally.
Hopefully I'll get around to making server maintenance a player-side background process soon. In the meantime, if you want to help the game run, use ENTER+P and type "master", then use ENTER+M and type "start" press ENTER at any time to end the process. there's currently no visual feedback yet, I promise it is working. I'll add visual feedback sometime soon.
