Simple but chaotic game, congrats on finishing and submitting! I like these clicker type games and it definately has a great theme, could be a whole game! I think there are a couple areas where it could be improved greatly, I'll try to elaborate as much as I can.
Music: Well, it's just a small loop, this should be some chill and not that loud background music, and you could maybe add a sound to papers, like when you're "tossing" them away after completion. Different sounds for the different papers could do wonders, little changes in the audio can go far.
Graphics: The papers have a great look, I loved them, but I couldn't really figure out what the background is. I assume it's a desk made of wood, but that could be improved if you decide to take this game further. Also, the text which tells you the number of the week moves under the "Week:-" part if it goes past by 9, so any double digit will go into a new row. The checkboxes are always on top of everything, if I got a "To do" paper and 2 other above it, I could still do the checking part. This is true for other papers, like 2 white paper on each other and I could sign the bottom one.
Gameplay: Well, the game is fairly beatable, I got to week 25 with almost 550 seconds left on the timer before I closed it. The "To do" papers could give a little less time, so you can't just skyrocket up and be fine whatever you do. Another idea would be that you substract time whenever the player missclicks and didn't hit a sign mark or a checkbox, this way you can't just click all over the papers, you will have to hit them exactly. Maybe a little bigger hitbox on the sign here part would be better for this, but you can always just try it and find the perfect settings.
I hope this helps you if you decide to take the game further, which I really hope you'll do!
