Weird
This wasn't too scary until the end, because it made me curious to whether or not he actually made it out of the strange world he was trapped in. The creatures were all very odd, and put in the mood where I think to myself "Damn I don't want to be there". If you're ever to make another horror flash let me give a word of advice. (this is just my opinion really)
Most people like things that are confusing, and that surrounds the viewer of fear, and curiosity. Not knowing is a great fear itself.
