The game is inspired by the old school retro platformers of the 80s.

You play as a black, two-dimensional cube in a simulated testing environment. Your only ability is to jump. You will need to pass all the tests rooms generated by Gustav. You will maybe find out what this strange simulation is and how to escape before Gustav kills you.

Your only goal is to reach the exit. As you do, the level is cleared.

Thousands of SEB instances were generated before you and died doing the same thing as you.

You are the latest SEB instance. Good luck.
