Very cool game with a heavy atmosphere!
I really like the art style and all the character designs. The music is well done too! After I woke up the second time, the silence in the beginning was very powerful as well. The story really made me feel like I wasn't treated well.
I kept looking around for something to find, but didn't find anything out of the main storyline. Tossing in a comment when you look at the noticeboard at school, for example, might make the game a bit more interactive and drive the player into the story even more.
Good luck on the other acts, if any! Curious to see how the story developes :).
