A short (though duration will vary considerably with skill) masocore 2D platformer with Atari 2600-inspired pixel art. Progress through five areas and overcome deadly obstacles in your search for the Troof. Whatever that is.
Some obstacles are deadly due to their unpredictable nature and are clearly intended to take you by surprise, though if you have fast enough reflexes and proceed with caution you can survive many of these even the first time you encounter them.
