An original concept, I always like those! I think the strongest suit of this game is its unique visual style, I really liked it.
Gameplay-wise, I think some more information could've been conveyed to the player in-game, like controls and how many photographs do I need for the level, how many did I already take, things like that. The timer also felt too fast, generally I would always have to repeat the level because I only had enough time once I knew where all of the objects were.
The audio was great, spooky but not annoying. The only issue was that it sometimes glitched for me, for example when selecting a level (might be my problem only, don't know).
In general, I would love to see with a bit more polished gameplay and UI, but keeping the unique visual style. I'd also welcome any other games with the same style.
