I have to give this a low score, because there's no way to guess the combination to the box by the river, unless you click on Walkthrough, which seems unfair. 'Sleep' backwards and twisted into numbers is too much of a stretch, as is the word jumble for the second box (maybe if there was picture of a harp somewhere?). Also the horse stalls hasp didn't really look like a lock, that kinda threw me a tad...
Aside from that, the rest of the puzzles, art, gameplay and music were quite nice.
Well, there's no guessing required, the clues were somewhat obvious. If you spell Sleep like it's written you aren't doing it right. The word jumble was simple, almost too simple. There's only one possible answer other than the one given. This was too easy for most of my players. Sorry.
Well, I have certainly played worse games. The art was nothing great, nor the story, but it was straight-forward and clear. The entire games was generally too easy EXCEPT for the lock box with letters. I had to go to the walkthrough for it, and I still don't understand WHY it was the way it was.
Also, more mood music. I didn't find this music creepy at all.
