Fun game! I like the photography theme, and thing it's a more thoughtful interaction model than shooting things with a gun. I kinda figured out the flying picture level, but it seemed to be a lot going on. Consider starting with fewer mechanics and layering them on as the player progresses, similar to what's done in the first level.
I had some difficulty reading the tips because they were very small, especially the notebook next to the camera. I also missed the "Press E to pick up the camera" message - can the player just pick that up by walking to it like the mushrooms and photos?
