This is a game created by me! The game is free and available for Windows and Linux.

As you are exploring some glaciers you fall into a chasm (rotko in finnish). Your goal is to survive the dangerously epic journey through the Earth. The chasms are randomly generated so every playthrough will be unique. Rotko is my first game that uses OpenGL and my first 3D game, and because of that the idea is pretty simple.
