I did not find the last one. I tried multiple times. I spam clicked everything. A good idea, but not a very fun concept in detail.
This concept might work very well if you had a random list of 5 things out of a bigger object pool you have to find every run. I think it would give a better learning curve and variety.
My GPU goes brrrrrrrrrr. Limiting the frame rate to 60hz or native framerate could help. Works for me in unity projects.
I really like the 3d art, level design and music, it feels coherent and fits well. Player controls, Interaction and feedback feel very good.
Only manko here is the camera rotation. It should be direct, instead of a lerped motion.
