I guess you had some fun adding all those plucky elements/harps movements and other characterisics sounds from thrillers ! It's very cinematic !
The ambiance is incredible from the start, really well executed, and that first violoins run is georgously thrilling !
The whole thing is super cinematic from start to finish. You developped different/recurring themes for different moments of the games that fits their location perfectly so superb job :)
Alter in the Basement was the highlight for me ! :D
I agree with BodoTheSerf : time stamps on YouTube video would be a big +
