They had a demo of this on steam I think... last year? Or somewhat recently anyway. It was way more addicting than I expected, even with just the limited demo options, so I'll be keeping an eye out for the release date. Nice to see a lot of different variety in buildings, etc here too.
I've enjoyed all SteamWorld games. It's amazing how they manage to nail the different genres/styles of game. It's reassuring seeing people create games out of passion; I'm happy to support them.
Steam even has a demo which I'm absolutely going to try out.
