Game Overview

I was the sole developer behind “Obby but you’re a balloon”, a wildly successful obstacle course game on Roblox.

Created in October 2024, the game twists the traditional Roblox “obby” genre by giving players a completely different form of movement. Instead of a standard character walking and jumping, you play as a literal balloon. Players have to inflate and deflate to float over massive gaps, dodge hazardous obstacles like monkeys with darts, collect bananas, and explore heavily themed environments alongside their friends.

It exploded in popularity shortly after launch and has since achieved incredible performance on the platform, racking up over 3,750,000 visits, over 15,000 favorites, and reaching thousands of concurrent players.

Technical & Design Highlights

As the solo developer, I was responsible for the entire pipeline from prototyping the core floating mechanics to full release and live operations:

  • Custom Player Controller: Completely overwrote the default Roblox character humanoid to support balloon physics, inflation/deflation states, and smooth floating mechanics.
  • Level Design: Built expansive, multi-biome levels that progressively introduce new mechanics while balancing difficulty for a very wide demographic of players.
  • Monetization & Engagement: Integrated engaging collectibles (bananas) and unlockable skins to drive player retention and long-term progression.
  • Performance Optimization: Carefully optimized the game to handle lots of floating physics objects at once without lagging on low-end mobile devices.
