Nice job! I know a lot of work goes into these projects, and you guys should be proud of your finished work. Some feedback for your consideration:
1) More player choices would be nice. It's little too "on rails" .
2) There's an old saying that what you can't see is often scarier than what you can. The final monster would be scarier if you didn't get quite as good a look at it in the end ... more shrouded in shadow, closer camera angle, faster cut-away, etc.
Just my opinion. Thanks for sharing your game, and keep up the good work.
