Awesome game!
Levels are quite great, especially third, where everything is black and white, and it really made me think that somewhere is hiding the danger, and any second i could be scared to death! Loved the music, especially 3d effect (volume fading down at the distance), really loved it, made game a lot immersive!
But, mall level dissapointed me, monster wasn't very scary, so i just went to her and wanted to get good screamer, but it didn't.
You should really add some depth to mall level, maybe something like in previous levels, where everything became darker and darker, i loved that effect!
Also, character controller stucks at any wall, as i know, it's easy to fix, if you just change friction on physic material to less, it will help i think.
But, overall, great horror game, made me scared of everything that could come to me, and you made it good! Would love to see your other games, really interested in your creations!
