A great concept that only half worked for me. Rolling downhill as a ridiculous smiling boulder is a lot of chaotic fun, I enjoyed that a lot! The strategy layer of setting up obstacles and investing in traps to stop your opponent from rolling downhill though? Never really could figure it out, and as a result the game was pretty stressful since the nuances of half the game was lost to me, making it hard to do very well. Still, rolling downhill is very fun despite the struggle with the strategy.
