I really enjoyed this, I've been playing it over and over again until I finally won. Great job, it's got good music, good game play and good graphics. I'm impressed.
I remember you had suggested on the stream a building that destroys other buildings. Just FYI I've included such a building now. The Castle (repurposed), it now absorbs a random nearby building upon placement. It's live on the current build, with quite a few more cards and changes. Cheers!
