Iter Vehemens ad Necem, or IVAN, is a unique roguelike game that immerses players in a perilous adventure filled with challenges. Set in a frozen world where sea travel is impossible, players must navigate an underground tunnel teeming with monsters and traps to deliver a crucial note. The game features classic roguelike elements such as turn-based combat, a straightforward interface, simple graphics, and the ever-looming threat of permadeath. Each playthrough offers a fresh experience, making it compelling for fans of the genre.

One standout feature of IVAN is the ability to recruit allies during gameplay, allowing players to give them names and commands, adding a layer of strategy. Commands can be whimsical, such as 'try a bit' and 'vomit,' contributing to the game's quirky charm. While the learning curve is steep, the gameplay remains engaging, as players face new challenges with each attempt, ensuring that IVAN remains a fun and unpredictable roguelike experience.
