Sorry to say so but I downloaded this yesterday and I appear to be getting the bug that prevents you getting past the assassin encounter. It doesn't appear to matter what I say or do, whether I have the explosives, or how high my intelligence and/or combat skills are nor even the magic skills of any of the princes. I always get the ending where you collapse after catching the mage with Garion and his men and the game says that's the end of the demo.
Ah. Alright thank you for letting me know that I wasn't actually hit with a bug for once, If there is a bug in something I'm almost always unlucky enough to come up against it! I guess the ending seemed a little abrupt, and potentially deadly, to me and since I'd just read about a problem that others had with that encounter (while trying to find out if I was just flat out doing something wrong) I assumed the usual had happened again. Good to know the issue this time was only me being a twit!
