I see that the engine you are using is somewhat limiting in terms of animation and gameplay. A lot of things are a little repetitive, but gets the message across. The game actually turns out quite scary, and I quite like the small puzzle parts of the game.
I wonder, what if I waste all my pictures before I reach the first cross? Am I just stuck?
In terms of story, I saw a nice start, I would love to see this expanded a lot more in the full release!
I see you use the same template as the game "Siren Head: Resurrection", which you should really try, he managed to use this template in so many creative ways, if you need inspiration that is a great place to look!
Anyway, great experience!
