Outer Time: The vocal and digital sounds that swell in and slide up a half step are extremely cool. I think it is such an awesome detail that you land on the groove of this track exactly at 1:00. That groove is definitely my favorite part of your entire OST.
Spin the Hourglass: The subdued synth melody makes me feel contemplative and focused which would be so good for a puzzle game like what you describe. I think it is so cool to hear how you can take the same instrumentation and apply it in such a different atmosphere and context. Very well done.
Inside the Falling Clock: This is a great concluding piece to your trilogy. The shattering effect works so well along with the ticking of the clock. The ending is abrupt, but works with the atmosphere you created!
Overall: The mixing you’ve done and your instrumentation choices are so on point. This would work so well in the game you describe and would elevate it to a next level experience for the player. Thank you so much for your work on this and thank you for sharing!
