I like the concept of an explorable sort of semi-sandbox you have going here and I think if you had more time to work on it and flesh it out it could be a really immersive bit of interactive story telling.
That being said: For the future, the dialog could use more depth & take all the time you need to take on art. Not bad for a class project I assume you did more or less by yourself. So Imagine what you'd be capable of if you weren't under such a strict deadline.
Honestly: If Dawnford: Day3653 popped up here in a year or two, I'd play it.
