INERTIA is a 2D Platform game about traversing a dangerous environment in zero-gravity. INERTIA was developed for PC as a student project in The Guildhall at Southern Methodist University. INERTIA became the $100,000 Grand Prize Winner for non-professionals in the 2011 Indie Game Challenge, as well as winning Achievement in Gameplay and Technical Achievement!

Narration by Adam Sessler


As a designer and programmer on a team of 5 student devs, I designed and edited levels and also programmed gameplay mechanics for INERTIA. I came up with the initial concept of INERTIA, upon which its creative direction and game design became a team effort. While working on INERTIA, I learned the development tools for the TorqueX 2D engine, including Torque 2D Game Builder and the XNA Game Studio API in C#.

Specifically, here is what I worked on:

Gameplay Systems

  • Inertia Mechanic (weightless floating + bouncing)


  • Layout + Obstacles
  • Collectibles
  • Tutorial Hints

Design Documentation

  • Gameplay Mechanics section of Game Design Document
  • Level Design Document for LEVEL 1


I designed and built LEVEL 1, which introduced players to the core mechanics of INERTIA. LEVEL 1 teaches players how to combine traditional platforming mechanics with the unique “Inertia” mechanic.

While I didn’t work directly on LEVEL 2 or 3, they are shown here to showcase more gameplay from INERTIA.
