Ahhhhhh. This game is definitly a gem. The yield mechanic is really well thought of, and the world you've painted is simple yet really effective. I love the art and feel of the game. With just some more polish to UI and such it could be a really solid full game! I really want to play more :)
I feel bad that this game barely has ratings for how good it is. I suggest next time making your game playable online. But again, wonderful game! You've done a real great job!
