How I Built a GeoGuessr Game for Super Mario Odyssey

The Idea

I wanted to build something different from the usual fan project. Instead of recreating gameplay, I asked a different question: How well do players actually remember the worlds of Super Mario Odyssey?

The result is OdysseyGuessr, a browser game inspired by GeoGuessr. Players receive a screenshot from one of the game's Kingdoms and must place a marker on the correct location. Every meter counts.

Features

The project includes:

• Browser-based gameplay
• Single-player with customizable rounds
• Real-time multiplayer with a 5,000 HP battle system
• Community-submitted locations
• Admin moderation tools

Challenges

One of the biggest challenges wasn't the gameplay-it was collecting interesting locations that were difficult but still fair. Watching players confidently choose the wrong cliff or rooftop has been surprisingly entertaining.

Feedback
