Reading your description for the theme of your game was kind of crazy to me, since I feel like we sort of came up with the same concept independently, and we both used Reaper which made it almost feel like I was seeing an alternate dimension version of myself haha. That being said the feel of our OSTs definitely sound much different.
Overall I enjoyed it, I think Winter Storm is my favorite due to the dramatic harmonic minor type stuff. It would've been cool to see some of these fleshed out a little more, but I totally understand how the time constraint can make that difficult. The instrument choice sounds nice as well
