It has achievemnt trophies you can collect. There are not too many HOS and some are regular (find the pen or hat) and some are shaddows of the items so it was not repetitious and there were other ways to gain inventory than the HOS.
I really liked this game. This is the second "awakening" game I've played. The first one, the dreamless castle, was good also. I've purchased moonfell wood now so I'm going to check it out.
I thought this game was fun and relaxing. The puzzles were pretty easy tho but thats what made it so relaxing I suppose. The music was not annoying either. :)
