The best entry in the jam for me so far. I really don't know how you manage to do all of that in 3 days. I managed to go to 170 product delivered where i was asked for 40 glass & 60 metal, with 4 production site destroyed during the previous 2 turns XD.
Music is perfect for the game. Pixel art is nice. If i wanted to be picky i could say that a pixelated interface would suit the game better.
Great job!
