I love these types of games and the controls here are fluid and intuitive. Playing on the MAC version I had a crash once the tile count hit somewhere past the 150 mark. But, had a fun time.
Some feedback would be I'd like to see goals related to railroad tracks, some endgame objective(s), and most importantly a shorter game. Right now it feels like a guided sandbox, but it'd be nice for it to be tighter since I felt like I was breaking the game with how it kept going. Dynamic visual indicators for town growth and numbers would also make it much easier to parse.
