Really great game! Got 10/10! The controls felt fine to me, and the paintings were really great for keeping the game challenging! I'm not sure how this would change the game, but what if you let the player turn the page themselves for the next painting? That way if the player wants to spend a couple extra seconds on the previous painting as it's being taken away, they can! This sacrifices some time that normally would've had for the next painting. And to balance this, you could have the paintings be shown for less time as well. There's definitely many ways to add more mechanics and other things to keep track of so really great job here!
Overall the execution and art was amazing! I had lots of fun playing!
