I liked the music and the look of the outdoor landscape. However, like darqwerful said, the text simply doesn't stay on screen long enough, so it's hard to follow the storyline. I spent most of my playtime first trying to open the door (which you said how on the gamepage) and then trying to find my way around. The darkness adds to the atmosphere, but makes it hard to understand where you are. I got to the school and to the rune training, where I fell of an edge after learning (?) three runes. Unsure if it was a bug or not, I replayed and fell off again. I don't know if there is a save function or not, so I'll leave it there. I see darqwerful progressed further than me, so I guess there is more to it.
The game and story has potential, but an advice would be to try to make it easy for the player to understand what's going on, and easy to do what they want to do. A large room with nothing in it may look nice, but hinders gameplay. I would rather get the Black magic temptation story than be stuck trying to walk up or down stairs.
