I LOVE this game!!! I can't wait for more worlds/levels to be added! It's so creative, with such a simple way to play but it makes you feel like you've accomplished a lot. There are so many biomes, enemies, and resources; it's a great casual game. It has the perfect balance of well paced progress and making you work to gather recources. The only downside is you have to watch a lot of adds to earn resources. I wish there was a paid version to limit the adds, I'd totally pay for this game!
