Amazing and fun game, can get really difficult but I think that's the point. You collect more and more gems, risk loosing them all while traveling to collect more, bump into something, lose a gem and make a dangerous run back near the saw. Fits the theme perfectly.
Game lets you be creative, once I saw that traps damage everyone and not just you, I began using it. Tried luring a goblin who stole my gem into a spike trap and inevitably failed xD. But I still felt smart for doing so and was happy to figure that out.
I also love the beautiful artstyle and the animations of gems being thrown.
