Thanks! There is actually ambient forest noise, but it's quite quiet so you may not have heard it. I considered some music for this, but my composing skills aren't where I'd like them to be in order to couple with the relaxing, almost contemplative pace of the game. I struggled a fair amount with the timer as well; in hindsight I should have changed it to a camera battery dying mechanic, which could display the time left when you have the camera out.
Thanks for taking the time to check it out!
