Sorry about that. F12 switches to fullscreen. I should have made that the default. The game assumes a bit of knowledge about Bard's Tale interface. The first letter of every option in the goblin camp chooses that option. So you need to use 'c' to create one or more characters. 'a' to add them to the party. 'e' to enter the woods. Definitely some work needs to be done on the UI.
