It's a good concept, but the graphics, the functionality (no game over when at 0 population) , the absence of features like woodcutters and other types of building, make this game pretty boring... and the music is melancholic (sort of) , which should be replaced by some "neutral-to-happy" songs. (yes, not only one)
There is A LOT of room to improve. But making this game as it is is still an achievement! ;)
