1) First thing I'd do would be to disconnect all the graphics rendering code from your World and Entity; it's going to be complicated enough without them :-)
2) I don't like that an Entity remember its index into the world. Let's revisit a typical roguelike data model:
> a World or a Level has a tilemap (floor, walls, or generally - a tight "grid" of walkable and non walkable scenery) and in addition - a number of entities, where every entity stays on one place in the grid.
You can have zero or more entities in the same slot - a goblin can stand over a pile of items, for instance.
3) Now let's think about the processes that happen. There are processes like movement, attack or picking things up. Let's take movement.
