🎮 Game Introduction

"Touch it! WarioWare" style ultra-fast minigame collection.

However, a single round you miss changes the history of humanity.

• ⏱️ 3 to 8 seconds per round — No explanations. Look at the screen and react immediately
• 🕰️ Chronological progression — Big Bang → Stone Age → Bronze Age → Middle Ages → Modern Era → Contemporary Era → Future
• 🦋 Butterfly effect — Failure is not a game over, but a different history
• 🎨 2D photorealistic style — A strange sense of dissonance created by AI-generated photorealistic images

✨ The ending is not set

The LLM reads the history you made and writes the narrative on the spot.

• 📖 No pre-written endings — Generated at runtime the moment the round ends, rather than pre-made branching
• 🎭 Your gameplay is the script — What you succeeded and failed at in which era becomes the material for the narrative as-is
• 🌠 Star Wars-style credit roll — Flows into a grand critique spanning the entire history of humanity, from the Big Bang to the future
• 🖼️ Ending images are also generated — A photorealistic image where the experienced events are fused into a single scene appears in the background
• 🔀 2ⁿ possible combinations — It's hard to see the same ending twice

World where the witch wasn't caught → "The witch survived and is now sitting next to you." World where the witch was caught → "The witch retreated into fairy tales, and magic was erased from the world."

💡 The game does not judge you. Failure is not described as 'doing poorly', but as history that unfolded that way.

Core Fun

| | | |:---|:---| | 🔥 Era-specific custom minigames | Lighting fire in the Stone Age, finding a witch in the Middle Ages, picking penicillin in the Modern Era | | 🔗 Experience historical causality | Experience "What if that hadn't happened back then?" with your own hands | | 🪞 Game failure penalty | Failing a minigame will affect gameplay in real-time. | | 🎲 Different ending every time | Success/failure combinations of 2ⁿ → Ending text and image generated at runtime |

Game Flow

🌌 Big Bang (Prologue) │ Failure → Game Over, start over from the Big Bang ▼ 🪨 Stone → 🏺 Bronze → ⚔️ Middle Ages → 🏭 Modern → 🌆 Contemporary → 🚀 Future │ Plays through all in fixed order ▼ 📜 Ending Credits (Star Wars-style roll) ▼ ✍️ Name the World → 🖼️ Permanently store in Gallery

3 Types of Minigames

| Type | Upon Failure | Example | |:---:|:---|:---| | ⚪ Normal | Just passes by | Rubbing hands, shoveling | | 🔵 Change | Flow continues, but reflected in the ending narrative and image | Inventing cars, hacking computers, stocks | | 🔴 Core | Goes straight to the ending | Lighting a fire, bronze smelting |

💀 Failed minigames leave penalties. Dust gets on the screen, rats scurry by, ghosts follow you — it continues until the end of the round.

Ending & Gallery

• 📝 Credit text — Gemini reads your run and describes an alternate history
• 🖼️ Ending image — Fuses and generates the experienced events into a single scene
• ✍️ Name the world — Directly name the history you just created
• 🏛️ Gallery — Image + credits + world name are saved as a single chunk

🔌 Completed even without an API — A fallback generator creates the script instead for generation.
