Instead copying the H-World engine feature list here (a copy is almost always out of date), I'll rather give a link to the official feature list:

A game engine needs a manual, otherwise noone can use it. The H-World manual tends to be out of date (better look at the comments inside the files of the example game module "The Jungle") but I've tried my best to write an useable manual:

The H-World engine is bundled with an example game called "The Jungle". It is a fairly classic plot: an adventurer arrived in a jungle village. Nearby there is an old temple, some ruins, a cave and kind of a dungeon. A perfect start for new adventures. Are there dangerous monsters there? Big treasures? World moving secrets? Find it out!
