Fun, simple, addictive!
I quite liked this game. It certainly brought together some elements of gameplay I never would have imagined, kind of like a real-time strategy imaged in 8-bit style. I had a bit of fun with this, but the only critique is the presence of a timer, which I assume is an integral part of the game. But maybe you should add a story mode, whereby you take over a map of a culture, then get promoted to another, more difficult map upon completion. OR maybe there should be an item on field that gives you more time to maximise your Culture.
Apart from that, I didn't find any real glitches, and found it to be a pretty enjoyable play! Thanks. =)
