Yes, it's a pity that due to our limited experience, we only have two part-time members working on development aside from localization tasks, so we were unable to incorporate music/sound effects before the deadline.
I understand that adding musical variations at emotional climaxes or intense moments would have been highly impressive. Even though the jam has ended, I still plan to ask a professional composer friend to create music for this game in the coming months. Thank you for your suggestion—please stay tuned for future updates!
