Monotony - Oh I like the use of foley here. Love how you made an ominous rhythm out of a clock, some knocking and some other assorted sounds. This is a very moody track. I'd definitely be on my guard if this were playing.
Opportunity - Nice riff and drums. I like how the electronic glitches from the first track seem to make an appearance again. Makes it feel like the world is coming apart a bit.
Didn't You Miss me? - I like the piano and strings in this. I also quite like the ambient wash of sound that resides behind it all. It provides a nice backdrop for everything that's happening.
The True Self - I dig the drums in this one. I always like it when there are a lot of nice fills.
You're Going Back - Ooh, this one is great. I love how wide this one sounds and that bass drop it opened with. It's also creepy in a lovely way.
Great stuff! My favourites are definitely Monotony (the foley and suspension build up here in great) and the game over theme.
