* '''Graphic effects'''. IVAN has probably more advanced graphics than any other roguelike. ”But graphics are useless in a roguelike!” you might exclaim. You would probably reconsider such an opinion when following a wounded and panicked monster according to its trail of blood. Besides that, you’ll face dynamically generated and animated flames, smoke, auras, weather effects, explosions, sources of coloured light and much more, even animated squares such as water.

* '''General Gameplay'''. IVAN brings gameplay issues further than most roguelikes, while still remaining easy to play. Besides the bodypart system and the material and equipment system there are such curiosities as 2x2 monsters, wandering mercenaries and slaves which you can recruit/buy, smiths and tailors who can repair broken equipment, and monsters which are able to reproduce. The game also features many different deities ranging from chaotic to neutral and lawful. Each god has its own specialities and altars, and you will be able to affect your own alignment by the way you play. And on the top of all that, IVAN’s storyline will keep you pumped with its unique events!
