The idea of a clock tower is conveyed perfectly in every song, almost like the gears of the tower are part of the music. The bass line is intense and threatening (in a good way) and the stage theme lines up well with the idea of a stealth game. The title theme is truly powerful stuff and leads into your other two tracks well, but it feels more like the opening to a horror game than a stealth game, imo. The boss theme is more on track with a MGS-styled game and definitely gives the impression of intense action, I just would have liked a bit more of a main melody to it to drive home the weight of the boss battle. That list bit is probably more my personal preference than anything - overall, solid OST and great work!
