Don't try this game on an evening before you need to wake up early. Wonderful game, extremely engrossing: everything you do is a choice between long-term utility and time until implementation - Do you make something that will do what you need for the next five minutes in 1 min of building or something that will do what you what you need for days with a 20 mins of building? Everything is a good choice, but some choices speed up your growth faster than others. I've had many nights where I've gotten sucked in and played for hours before realizing how late it is. Games with exponential growth curves that are able to still achieve balance create such an exhilarating feeling of progress.
