Thank you for reaching out and for your keen observation.
The playlist indeed consists of 13 tracks on the primary platform, along with 4 additional videos, bringing the total to 17.
Regarding the music, while the top 3 tracks were specifically created during the jam, the remaining pieces were composed prior, as part of our ongoing efforts to experiment with unique musical structures, such as palindromic sequences, which we’ve incorporated into several of our projects. This aligns with our broader creative vision, ensuring a cohesive yet innovative soundscape for each game.
