Damn, that's why we need playtesters. I wasn't even aware that throwing stuff from the ledge could do something like that. There are other means to leave the tavern, but two ways for underleveled Dirk rely on items and these can be dropped in the wrong place! Back to the drawing board!
Thank you for a playthrough, I sure hope that I'll be able to create more levels faster now that I have better tools to do it. Cheers!
