Thank you very much! By the time I saw this, I'd found all but the final image.
So. I'm not expecting you to change this, simply letting you know my opinion...
If you're going to have hidden things to find, in areas that you aren't going to have permanent access to (like the initial house), you really should allow those hidden things to be found in any order.
The fact that you have to find them in a specific order, and won't be able to get back there to search for them later, means some players are going to just pause the game and search until they find them all, which in my case took hours because I didn't KNOW that they were appearing one at a time. I assumed, having THOROUGHLY searched the mc's room and already found 2, and clicked on every single square centimeter of screenspace, that I didn't need to go back and keep looking in the mc's room...
Very frustrating in that regard.
Definitely like the game, though!
