I'm actually, kinda torn at the moment. The subject of the game was extraordinary. The History lesson/vacation part of it. I felt like a tourist. The scenery was beautiful and the folklore was educational. For that, I applaud you.
However, I come to NG to play games and get medals, and that's where I'm rather disappointed. I understand your reasoning behind not wanting a walkthrough, and I respect that. Even though you added a "Spoiler free" icon to sorta help players out, it was of no use to me. Your "Hot spot" icon was very helpful, however. Unfortunately, it didn't help me get 4 of the medals. One, obviously, from getting all of the others. That's 3 places that I apparently missed. Despite the medals, that's 3 places I'll never see. I finished the game in which voids the 4th medal.
Don't get me wrong. Again, I love what you've done here. It's just that it's going to be conflicting with people. Some will be in it for the story and pictures aspect of it, and some for the game aspect.
I tried to reap the benefits of both, but failed in the end. It's quite possible that I could have done something wrong myself. I just doubt that I'll be the only one to miss out on some of the rewards from both aspects.
Good job, and I'm looking forward to the 2nd half.
