Secondly, 0.5 has no save support - the current addition is RF multiplayer (which works very well 2-player, btw). Due to 3/4-player not working and a bunch of other stuff, there's no release for 0.5 yet.
Yep - it's still private. The guys at the meetup last week got a look, but it's not gonna be released quite yet. Hopefully wont be long (look at Genemu!)
