The Lighthouse, submitted for the 2008 IF Competition, is probably the easiest IF game ever created.
The goal as stated in the introduction is to turn on the light in the lighthouse. Beyond the introduction there is very little description. All the places have names, but there is only the most cursory description of each room. Every object, when examined, returns the stock response, "There is nothing special about X."
Technically there were no flaws in the game. There was however, no challenge either. The old Infocom sampler offered more in the way of interaction.
Perhaps, as a previous reviewer surmised this was an exercise on the part of the authors who were trying to learn Inform. I hope this is the case. If the authors read this review, I would encourage them to continue creating IF after this first rather timid step.
