You are an earth shaping titan, and a band of adventurers have come to you for help, they desperately need to get to a neighboring town because one of the adventurers sister is incredibly sick and needs medicine. but they cannot as a massive storm has destroyed all paths there, normally you don't meddle with human affairs but their story touched your big stony heart, so you journey with them and create a path for them to get to the village.

the game is a VR "sculpting" kind of game, sort of like lemmings you need to sculpt the land into a safe path for the adventurers, while keeping an eye out for potential hazards that could harm them, with each area ramping up in difficulty,for example you can dig channels to divert raging water in a different direction to create a path for them, or break down fallen trees so they can get past, its up to you how you want to direct them.

keep on the look out for stranded people, they are hidden in dangerous areas and may need a giant helping hand.
