Hi! I am a fan of escape room games so I was excited to give your game a try.
First of all, I think your game have some very original ideas! I didn't expect it to be knowledge based at first :D I spent some time trying to understand what to do with the safe only then realising that I already have everything to solve it. That's smart! The way monster attacks actually helps you try to think harder, I also enjoyed that (I was like "all right, there something I am missing, let's look again" instead of being lost). [some SPOILERS ahead] I also believe I managed to escape, though I at first I didn't understand how I managed to "Kill", I first believed it was made with a torch. Maybe there could be some interaction sound, like a crowbar hit, to make it clearer? Some sound effects in general would be awesome to have!
I also found controls to be a bit challenging, especially as I expected that clicking on an object doesn't mean that I immediately use it. Combining paper pieces was also suddenly quite hard haha, as these pixels were not that easy to distinguish :)
I also think it would be awesome to have some additional story that explains the situation I found myself in! There seems to be a cool premise as I don't remember who I am and what happened, but to have a grand reveal would be really cool to have.
I had fun playing your game! Thanks :)
