I got this at the Time Machine sale for my T100 touchscreen tablet because I read that it has tablet mode. I've installed it and turned on tablet mode but I can't seem to figure out how to move. Anyone have any ideas?

I don't know anything about the tablet version. The official website (www.grimrock.net) will probably have an info page or forum thread though.

You've probably solved this by now, but I think there's an option in the menu to have arrows on screen to "click" (i.e. touch on tablet) to move rather than using the keyboard.
