From developer's website:

Fellow adventurer, turn back while you can! For here begins the
roguelike Iter Vehemens ad Necem, a Violent Road to Death. If you
choose to travel along it, you will dive into countless exciting
adventures to gain items of great magic, attain powerful equipment
made of mysterious materials, bathe in the blessings of mighty gods
and recruit loyal allies of various shapes and sizes. Unfortunately,
along the way you will also often be dangerously injured, poisoned,
catch numerous diseases, lose several limbs and transform into
manifold different kinds of pitiful creatures in the darkest depths
of hostile dungeons. And, at the end of the road, you are bound to
perish in a most gruesome and painful way. Don't say we didn't warn
you.
