The design of the creature is great and the fact it turns into other people is also cool just if he gets close behind you music starts playing so I found my self not looking around for him seeing as I knew an audio que was going to play getting rid of that would be a good way. With that I think the game would be much more suspenseful making it somewhat scarier but like I said with how many other people there are you have a sense of security even though a false one it is still there so making odd and unexpected occurrences happen like the people disappearing for a short time or the scenery and music changing to something horrific and intense (also for a short time) could make it a bit more scary. That's my opinion though this is your game and a good one at that.
