This is probably one of my favorite entries so far. I can say I was immersed into the world as it felt like a believable place. Also, I'm not only a sucker for 2D/3D hybrid graphics, but low poly 3D is becoming one of my favorite aesthetics.
Game play wise, it was fun and I appreciate how you incorporated some platforming elements which was essential to take pictures of certain things. Personally, though, I didn't find enough incentive for taking pictures (I did anyways since that's what the game wanted me to do). I think there's room to expand on that feature - maybe there's a score and/or currency system, maybe you need to take certain pictures to progress to the next area.
Atmosphere wise, the game was pretty relaxing and the music was perfect for the environment.
Great work overall!

I loved how you introduced the big foot mystery as you scale up the mountain, and how it ends up tying into the plot - it was pretty wholesome.
