This is actually quite entertaining, a few things I would want to point out:
1) The tutorial is a bit iffy, it's very well designed UI-wise but it doesn't really teach the player what to do so I had to pick up on the fly. Which was fine for me but can be problematic for slower learners. I think you need to be more specific in the teaching the player the objectives of the game.
2) Your art and sound is on point, sounds very good as a whole game. If anything, you could always add more polish by having more sound effects when filling shelves, pretty sure there were no sound effects when filling shelves.
3) The RNG nature of the tapes box lends itself a more casual-approach of this game, which fits the game jam nature and I think you did it justice. By also omitting, whether intentional or not, the actual number count of tapes left on the shelves too, you remove a lot of the strategic aspect of the game (having to plan what shelves to fill etc.) which I think also fits the casual nature.
With that said, I've only played on the default difficulty so it mileage might vary.
4) Simple game loop with simple mechanics. I think you've nailed it by having only a few things to worry about and allowing yourself more time for art, music and polish in the entire game. It looks and feels good to play.
However, I am unsure as to how to take this game further. Your current game design feels like it fits some other games that focus on managing chaos (like Diner Dash, first thing to mind) which is something I have not explored much so I won't comment on. Consequently, I feel like the rewind tape mechanic is supposed to fit that but I'm also not sure how much it contributes.
On one hand, its a neat feature but on the other, I'm unsure how much it contributes to the gameplay as a whole.
Regardless though - this is a fun little nifty piece! If you give it some more love, more time and more fine-tuning, you could definitely port this on mobile just to see how it goes. Cheerios man!
