While I have seen the "revive a loved one" thing happen a few too many times in horror lately, you do have a lot of unique thinsg going for this one. Your puzzles flow fairly naturally and are quite interesting, particualrly the snake bit, which I found rather interesting. And using the notebook was a nice idea.
However, what the game lacks is polish. The fonts are too standard, things seem a bit jittery, and some things are just delivered too matter-of-factly instead of being given time to work. The confrontation in the notebook, for instance, could be much, much more intense than it is, and is kind of undermined by sending you on a short, ultimately pointless fetch quest immediately after.
There's a lot of cool things here, and you should be proud of those.And I do realize this is a student project, so take my criticisms less as "this is bad" and more as "Keep in mind for next time": With the right amount of polish, there's a really cool, spooky experience in to be found here!
