Hi, after several trials I managed to click on the right spot on the map and continued until the Epilogue, thanks :-) (It would be perhaps fine to have some kind of warning before using the map for the fist time, similar to the message aobut spacebar...)
In general, I am afraid the game is fun only for those who know the parodied model, otherwise there are tons of details in the text (and very few CG) it is simple to get lost or to lost interest to play, or better to say, read, further.
