I also find the lamp a fun aspect of the game. Whats great is that you can tweak the game to your playing style, so if you don't like it, you can change it!
Back on topic, a feature that I think would be kinda cool is a high score table, that shows the characters who made it furthest, what level they where, and perhaps even a way to name your player. That would make the dungeon romps a little more memorable.
There are other things, but I would like to see the plugin guide first to see just how difficult it might be to make some of them. I really would like a dialog, with choices, or at the beginning of the game a way to choose your character.
