I love the masks are used in various ways to solve certain puzzles. I struggled on some of the puzzles but I got through many of them. Although, that puzzle with multiple platforms and grey boxes on the sides was very tricky for me to solve and I can't get past it at all.
I didn't know how to zoom 100% to see the dialogue UI though so I just flat out skimmed the dialogue. But this is still a really fun game despite the UI issue and the puzzle difficulty in later levels.
Also, the curtains closing as a way to communicate failure was a really amazing addition to the game.
