It's pretty good, i like the atmosphere, and some of the more psycological scares were nice (like when things moved around)
but i would say that the enemy is kinda unfair. I died twice to it and neither times did i hear any breathing before dying, so it seems like you need to be standing still BEFORE you even know it's there. Which is a bit ridiculous, especially since death means starting from the very beginning.
But overall, i enjoyed it.
