Game breaking bug about a half hour in, maybe less. There is a drawbridge wlthat you lower by flipping a switch, but you can elect to pass under the drawbridge and continue going right. A few screens over there will be another exit to the right which the map indicates is a room transition, but when you try to go through it you hit an invisible wall. Waited a long time to play this game, and really want to get the full experience, even if it is gained by playing an inferior android port.
