Very nice production values! And good explanations too.
I would consider moving the wheel of source code to the end of the show, though. Now you start with two small features (a monster, a piece of source code) and then the main feature. I personally would prefer having the main feature in the middle with the monster as an appetiser and the source code as a more technical epilogue.
I'm interested in seeing what's going to happen. I'm not familiar with uMoria, and to be frank ... it seems a little bit boring after seeing one-and-a-half session. As far as I've seen, there's very little to pick up in the dungeon, the dungeon floors are very large without something handy like DC:SS's auto-epxlore fuction, the monsters don't appear to have much individuality, and the strategy for beating them seems quite constant. But of course I realise that a lot of that might just be because we're only on the first level, so as I said: I'm interested in seeing what's going to happen!
