Great game! I had no idea what I was looking for, but I had such a good time with this one. It is amazingly polished (yes) for a free game. Totally crazy! I played through it 6 times in a row, but I can't seem to beat Impossible mode. I really love the progression, the design, the little bits of history thrown in. So many nice touches! I'm really happy with this game and will recommend it to my friends. Thank you for this!
