I understand that an iOS or Android app is a lot of work and may not happen in the near future.
However, as an alternate solution, could we have a more mobile-friendly website ? For now, the site does not seem to have any mobile-specific layout or version. I feel the game page would only need a few adjustment to be good enough to play on mobile.
Good work on the site anyway ! I just discovered it and I'm quite happy to play Dominion again.
