The game does take themes from the Kalevala, but one thing I felt I really dropped the ball on was explaining how it tied in with the story. It's something I will definitely be resolving for the new release.
As for social media, I've never been one for that. You can find my account on Twitter but I haven't updated it in a long time. :) Kickstarters and other crowd funding, I have considered. But I was unsure if there was enough interest to even warrant asking for that.
I'm really bad at advertising and I work on my games alone when I have free time/ability to commit, which tends to make my release schedule very slow. (Legend was released in 2012, and before that my last big game was released back in 2005!) I would like to expand that effort but it's only been until recently I've been entertaining such an idea.
I'm glad you enjoyed the original and are looking forward to Legacy, though. That means a lot to me; Honestly, I make these games for my enjoyment, really, but it also makes me feel so good to realize that others enjoy them just as much (if not more).
