I think I got to the end of the main campaign, and it's been a fun few days, though it definitely looks like more is coming, and I've still got a bit more to unlock. Haven't scrounged up enough cash yet, but I'll definitely upgrade to support development when I do. Really nice work on the game.
Just a minor issue: I believe that one item in the treasury still has its numbers listed out of order. Otherwise, things worked generally well, and I thoroughly enjoyed my time playing.
