The premise is as simple as it is ludicrous: you're an angry mountain man who decides to vent his anger by crushing an otherwise-quiet hillside village with boulders. The boulders control sort of like Pachinko balls, except you can adjust their trajectory from time to time. The boulders are also notably unlike Pachinko balls in that they destroy everything they come into contact with, leading to some satisfying destruction combos (think of a boulder hitting a goat hitting a biplane hitting a cop car, and then all of them hitting a gas station) if you get a really good run going.
The town-smashing is elegantly broken up with short, surprisingly entertaining combat sections that task your mountain man with fighting off park rangers, SWAT team members, and, eventually jet bombers. Check it out here, and be sure to watch out for the goddamn Yetis.
