I since built a new engine for both the sequel (Sovereign) and a substantial Underworld Upgrade. After a long silence I posted a first of a series of entries that will cover the work over the past year, as well as future developments.
I haven't really written one yet. Other than my paper todoes. Since I rebuilt the whole thing pretty much everything changed one way or another (other than the images). Stores, character creation, the way quests are handled, inventory, walking (fluid transitions are an option now) and of course combat and casting as shown in this update... That's off the top of my head.
I know it's more of a design decision than anything, but the option to use the mouse instead of using only the keyboard would be nice. Call me "un-hardcore", but clicking and dragging items between members feels less tedious than playing keyboard-piano.
