Ossuary – a video game based on the parody religion of Discordianism. In contrast to traditional teachings, this cult deifies Chaos and disorder, and this is the basis of the gameplay of the project. The protagonist is a soul living in the underworld, where everything is boring and dull. Therefore, the main character begins to collect sins and give them to others, returning them to their natural state. The game features mechanics of various genres, from puzzles to visual novels. For example, the traditional gameplay here is simple – the user moves between locations, carries small objects and enters into dialogues with characters. Conversations are an important part of the gameplay, as they allow you to advance the plot.

Ossuary has 6 endings, depending on the protagonist's decisions and actions. Each ending reveals one of the main principles of Discordianism to the gamer. All endings can be unlocked in less than 2 hours, thanks to a short storyline. The graphics here are stylized as old video games that were released on cartridges. The levels are painted black, and the characters and details of the setting are white, the color of bones. And to emphasize the atmosphere of parody and the meaninglessness of many rules of human society, the developers added numerous jokes. Among other things, there are 26 achievements that can be obtained for fulfilling special conditions.
