i really enjoyed your game (very unique and surprisingly fun!), and i think it would make up for a really good anxiety-ness simulator!! :D (just suggestions, no pressure!)
- you could make the mail randomly generated (so that the letters "never" repeat)
- have a biggier and tickier clock (so it's more anxious, of course!)
also the timer rn feels kinda detached from what you're doing, so maybe make it like 30 seconds per envelope? (so you would go to the next envelope only after finding a match to the previous one? or smth?) - have heavier music (the one right now totally doesn't fit doing federal crimes)
- maybe even make the hands more panic-y, maybe shaky even when you're close to running out of time
so what do you think?
