Yorevyn

What future will your choices leave behind?

Yorevyn is a small, history-inspired choice game. Visit the Classical World and Modern World, talk with a dramatized Julius Caesar and fictional scientist Dr Mira Vale, and weigh two dilemmas about water and atomic energy. Your decisions change ecology, technology and timeline stability.

Choose your traveller
Play as an Explorer, Historian, Inventor or Conservator, each with different perks. The era map also includes restoration samples and previews; it is not eight separate story chapters.

Restore relics and grow your town
Use Clean, Align, Fill and Paint on symbolic restoration schematics. Finish all four tools to complete a repair, earn rewards and work through five quests. Upgrade five town buildings and collect the coins and knowledge they produce over time. Town income builds while you are away, up to an eight-hour cap.

See the impact
Follow a projected path towards A Greener World, A Technological Leap or A World in Crisis. To reach an ending, answer both dilemmas and bring at least three town buildings to level 3. Your choices determine the projected future; your earned town progress completes the journey.

Free with ads; optional Premium
The whole game is available without a purchase or watching a rewarded ad. Premium is one permanent purchase: it removes all ads and doubles town coin and knowledge production. An optional rewarded ad gives double town production for one real-time hour. The boosts do not stack, and Premium owners see no rewarded offer. Other rewards are not doubled. There is no subscription.

An interstitial may play when you choose Place in Museum after a completed restoration. None play during tool actions or dialogue, none in your first ten active-play minutes, and at most one every five minutes after that.

For families aged 9 and up
The first-launch year-of-birth question can be skipped; the answer stays on your device. A grown-up answers a multiplication question before Premium checkout. Restore purchases and Privacy policy are in Settings. There is no chat or game account.

Gameplay works offline and progress saves on your device. Ads, buying Premium and restoring purchases need an internet connection.

Historical settings are mixed with fictional conversations, objects and outcomes. Static AI-generated art uses Google Flow (Nano Banana Pro), ChatGPT image generation, the Google Antigravity image tool and built-in imagegen; text uses Gemini 3.8 Flash in Google Antigravity. There is no in-app generative AI and no game audio.
