I really like the idea of using actual audio from podcasts. Having actual readings of the philosophy in the game while your walking around the table, for example, really brings out the philosophical point. This kind of thing could be really useful in helping students understand difficult philosophical content by letting them explore it at their own pace.

My suggestions would be to give a little more direction to the player, improve the integration of the audio, and polish the art assets. It took me a little too long to figure out that there was a light switch in the corner of the first room. As for the audio, it was a little jarring when it first started playing.

I'm happy someone tried to tackle a particularly difficult philosophical area.
