Fallowite

You arrive for the Lantern Festival and find the valley silent. The houses, the lanterns and the people are all gone, sealed overnight in glittering keepstones deep in the cave below.

Descend, bring them home, and rebuild the town one house at a time. Then set out, because it isn't the only town that went quiet.

A 16-bit style RPG. Turn-based dungeons, a town that grows back around you, no ads.
