I'm gonna pay for atleast 1 month, just to check out 1.20.
to be honest, i'm enjoying this game at 1.19a, and they've been working very hard to improve a lot. I liked the game back when it was 1.0, it was different, just the bugginess got me. I'm glad they've done a lot to make it even more enjoyable, and figgured since I've been playing for free for a year-ish, I'd spend 12-15 bucks for another month to see where they're going.
