I read the descriptions again today and the OST makes more sense. I will be honest, the first time I read the descriptions quickly because there is little time to rate all submissions. I now see the odd time signatures and reverse sounds. I believe it's my turn to fully explain how I rated the correlation.
When I saw the theme "Tick Tock..." I expected to either feel a sense of urgency or a sense of time passing slowly. Since I couldn't really find that element in the OST "Temporal Tower" without the description, I was confused with the correlation.
I spotted OSTs that correlated very well to the theme thanks to the sense of urgency or slow pace, the orchestration fitted the idea presented and the genre of game fitted the theme tick tock too. Notable types of imaginary games are bomb disarming, shooter, speedrunning, puzzles.
The OST "Temporal Tower" is orchestrated beautifully, it fits the RPG theme. However, in my opinion, the RPG genre must be the hardest one to correlate with the theme "Tick Tock...". RPGs have relaxing and tense moments, just like Temporal Tower. They have more variety and thus it's harder to stay consistent with the theme. In contrary, for example the shooter genre is never relaxing, the player always maintains a state of situational awareness and sense of urgency.
I am interested to know how you rate the theme.
