Upgrade Farm

In Upgrade Farm, you defend your treasure chests from growing groups of different farm animals. Why do you own the treasure chests? No idea. Why do you defend them from animals? Because it is fun! There are various upgrade options that you can buy with earned gold so that you can fight the ever increasing hordes. The higher your level, the stronger the animals become. As you progress through the game, you'll unlock new, stronger, opponents who are even more interested in your treasure chests! This game is my first app, so I'm grateful for any factual feedback.
