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.
There are various graphic effects in the game, such as bloom and motion blur, as I am interested in creating complex graphics. However, the effects are not achieved by using shaders but plain OpenGL 1.1. Therefore the effects are a little heavy and need a decent graphics card.
This game also has an online scoreboard for the endless mode.
