Okay, after playing DiabloRL, I like what I see. The only big features that I want implemented are already listed in the 'to do' list, so I don't have much to say -- just have fun making it work! :3
However, I DID see one problem: the enemies don't 'swarm'. In Diablo 2, when you fight, melee enemies who can't reach you will circle around you, eventually attacking you from all directions. In DiabloRL, they sit behind whomever got to you first, meaning you'll have (at most) 3 enemies attacking you at once. (Ranged enemies usually just fire from where they are.)
I presume that NPC 'allies' will eventually be part of the game, as well?
And I can't wait to see your Carceri Engine. If it's what it's cracked up to be, I can use it to make FalloutRL. :3
