The Mansion-
The shrill piano is excellent for getting across the fearful feeling you were trying to capture, along with the short, low strings that come in later on. Personally when it comes to fearful/horror music I tend to prefer a more open arrangement, so I found the groovy beat a bit distracting from the intended feeling- but for an exciting game level, I can understand the draw there.
The Street-
The vocal synth adds a nice ambience. Lots of interesting parts drawing the ear's attention. Like the little running piano motif that returns from the first piece. The crunchy bits add to a very appropriate industrial vibe.
The Lake-
Ooo, a really good shift into that stillness feeling. It definitely feels like the calm in the storm. I will say that while I found the other two a bit heavy in instrumentation, that helps this track to stand out against them, and that's a great contrast. I like how there's this build of desperation at the end to hold on to the memories, and I appreciate the sense of struggle between joy and that desperate gripping feeling. Again, I notice the downward repeating piano motif throughout. The reversing sounds at the end- perfect for the theme of looking on the past.
The Hall-
The start feels like a great climax of conflict feel after The Lake. That being said, after the beginning it sounds more understated than I would expect. I would expect it to be bigger and more devastating, probably swapping it with the energy that the first piece had. I don't get the sense of "self-destruction". I will say I notice it is very repetitive, which could represent getting stuck in a pattern, which I appreciate.
The End-
I notice the reversals and light piano from The Lake. Heartbeat, clearly representing "weigh(ing) heavy on the heart". A lot of back and forth between a bright happy sound and the more uncomfortable creepy tone. I think I wish there was more of a bittersweet vibe here, rather than creepy/unsettling. Love the little happy ending cadence that goes back into the heartbeat.
Love how you had smooth transitions between each piece. Overall there was a lot of talent and passion in all of the tracks. I was impressed with the control of harmony and dissonance. It sounded well put together and flowed well, very cohesive, which can be hard to manage within a limited timeframe. Great job!
