This is a unique concept and goes together very well with the theme well done!
It's enjoyable to setup a farm and watch it grow, but the day and night systems were weird. It seemed that all of a sudden it would be night and then 5 seconds later day. It would have been nice to be eased into it.
The 3D graphics were good, sounds and music were great as well. The sounds could be a bit better, like walking for instance, you here the same sound over and over again. Would have been nice to play some different walk sounds at random or just randomly set the pitch.
Overall great game a little rough around the edges, but works very well.
