Thank you and glad you enjoyed the game! Taking photos was such an ingenious way to help solve the puzzles, even we hadn't thought of that. It would be interesting if we could incorporate that into the game as well, think of them as haunted photos that contain special information, that would be fun.
Quick resuming is a nice idea as well. Thanks for that!
P.S. We tried to make the models and rendering as optimised as we could, so it's such a relief that our effort paid off!
