Very fun, personally like the built in balancing act between deliveries forcing the sale of turrets at base cost, which rewards large numbers of un-upgraded turrets, and the weight, which rewards smaller numbers of upgraded ones. Some bugs, as others have mentioned, and while they do have a significant impact on the game, they're easily fixed by selling the bugged turrets, and don't make the game unplayable. As tower defense games go, this is probably one of the best that I've seen at this scale, especially given that it's free.
