Been a while since I played a VN! I loved the painted backgrounds - would have been great if there were more (several were missing). A couple of times the menu options were only readable when moused-over, the FG and BG were too similar (I think) to read until highlighted, and in one of the longer text boxes the text ran off the screen.
Awesome to see a mac version of an executable - that has prevented me from playing a few of the submissions unfortunately.
It seemed a bit loose on the theme. But it was philosophy at least.
