Iter Vehemens ad Necem (IVAN, for short) is Latin for 'Violent Road to Death', which seems to describe the game pretty well. The game is extremely difficult. You can't make multiple saves. If you die, you can't resume your game from a previous point; you have to start over. Although this causes much frustration at certain points, it makes the game much more exciting since you have only one chance to live or die.
Your day started out just like any other. You woke up, climbed trees, gathered bananas, chased monkeys that stole those bananas, and finally distributed the bananas throughout the village. And just as you are about to enjoy your free time by taking a dip in the nearby crocodile bay, you are led directly to the viceroy of the colony, Richel Decos. He tells you that he suspects that his enemies are plotting against him and intercepting his messages before they can reach the central government. Your mission is to directly deliver this letter. To reach your destination, you must travel through monster-infested underground tunnels.
IVAN works in the same way as any other RPG. You control a character, who moves and attacks using the direction keys. IVAN's gameplay, however, is very unique. Throughout the game, you can catch diseases, be poisoned, lose limbs, and transform into different creatures. Every game you start will be different, because the maps are randomly generated. You'll never have the exact same challenge twice. IVAN is one of the best, if not the best, RPGs available. If you're looking for a freeware RPG, this is the one to get.
