Hello, guys.

I am new here. I am thinking 'bout early access. May you tell me what is the state of game now? Is it playable? Will I have fun or will I strugggle with interface or bugs? I know that this is not finished game but I wander what state of game is it now? What content is missing? Is it closer to Alpha or to Beta?
And: If I start to play now, will savegames compatibile with next patches?

Thanks for repy in advance, regards.
