🤥 Theme: 30 Seconds of Lies

Create content (an app, game, or tool) that finishes its playtime or operation in about 30 seconds.

Include a positive, funny “lie” (a fake or fictional element).

You don't need to make a masterpiece — aim for about 3 days of total production time. 

One-shot ideas, joke tools, anything goes!

💡 Interpretation of the Theme (Examples)

🎮 Games

  • Lying Rules: The screen says "Jump to dodge!", but if you jump, it's Game Over (an unfair game that ends in 30s).
  • Endure: A defense game where you protect the truth from fake news or enemy attacks for just 30 seconds.
  • Speedrun: A game where you must complete a "perfect fake alibi" within 30 seconds.

📱 Tools

  • Fake Generator: An AI tool that generates a "obviously made-up excuse for being late" (e.g., "An alien blocked the road...") in 30 seconds.
  • Joke Tool: A "Cat Translator" with a 30-second trial. After 30 seconds, it displays: "Free trial over! Please pay 3 tunas to continue."
  • Scam Experience: A simulator of a fake "You won 100 million yen!" site.
    • The site displays a progress bar that reads: “Scan this QR code to claim! (30 seconds remaining).”
    • When actually scanned, it simply shows a text warning: “Please be careful of scams.”

🤖 AI / Python

  • Hallucination: A chatbot that confidently tells a non-existent history or fake trivia.
