A very interesting concept. I managed to get some requests right :D. but not all of them. It was very difficult for me.
A bit more leeway, with guesses would have helped in my opinion. for example if you got 50% right, get one extra chance and maybe a checkmark on the mask that was correctly guessed or a crossout if it was wrong.
The artwork gives the game a very mysterious and bit of a melancholic touch.
Interesting experience and good game :)
