Excellent concept! I think it really captures the theme well while still being unique.
The controls leave something to be desired. I would sometimes fail because I tried to jump with W instead of Space; there's no reason they can't both be jump. I also think TAB or Q or something should also open the map because M was out of place by itself. The mouse shouldn't pan the camera — WASD should. I had a few frustrating moments where I photographed the wrong object or I would overshoot the object because panning the camera was too awkward.
It's possible the game would be better overall if there just wasn't a map or a camera mode at all, and it instead was always focused on the player. Take photos by holding right click to activate a camera reticle that freely moves within the screen focused on the player, release right click to capture. Place objects by left clicking on the screen, and have a hotbar to select the object to place. The same controls could be used for both the camera zoom and the hotbar.
One thing I really liked that I didn't expect to was just the hard cut from one level to the next lol. The satisfying door shutting sound, the character teleporting to a brand new area, and the suddenness of it gave me an exciting feeling... I don't know how to explain it.
I enjoyed the puzzles overall, I can't believe you were able to make light-based puzzles in such a short timespan. Well done! 💙
