I really love this game.
It's different, in many ways:
The artwork is a bit creepy but interesting, it's refreshing. It's not too easy, which is good, nor it's too difficult (and if you don't know what to do, it becomes boring). I can't say much about the music, because I rarely play any games with volume.
I like point and click adventures, but I easily get bored of them (because I end up seeing them meaningless, too hard or too cliché). With Nekra Psaria didn't happen. I just love playing it. For me, it's the perfect point and click.
