Field notes
The game starts with a Jōmon-era production loop: tapping a torii yields one rice koku, then buildings take over recurring production. Upgrades are framed as historical items and reforms rather than generic numerical boosts. The stated content spans 15 periods, from Jōmon through Reiwa, and the interface includes English and Spanish controls alongside save, share, and reset actions.
