Nice Game, I like the graphics and the concept. I couldn't understand how to rewind the tapes..

I was pressing E and I make a shop mess.

if you wanna try my game is https://misterm.itch.io/mixtape-match , Thanks

The art for this is really nice, as is the sound design. The gameplay loop is simple but polished. As other people have said the tutorial could use an extra line or two but other than that the concept feels rather complete. Well done for including a difficulty slider as well, options like that are always appreciated. 
Excellent job!

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!

Writing comments as I play:

• The tutorial is not very helpful. It tells me the controls but I have no clue how the gameplay works.
• I'm just thrown in, but I can learn pretty quickly anyway. It only took me a few minutes which is great.
• I love this art! The covers for the tapes are super fun to look at.
• The gameplay is fun! I love it. I wish the difficulty ramped up a little faster, though.
• What's the point of throwing tapes? I can't seem to throw them into shelves
• Also, I just want to say that this game is awesome, but the cover art and main menu do not look like the game at all. It's cool, but the cover and main menu sell a horror feel with the darkness and the one light screen, plus it's 3D while the game is 2D. This disconnect just might confuse players who are looking for a different type of game.

All in all, solid entry! The gameplay was fun and addicting, and the art was great. Good work!

This is the most fun entry I've played so far!
Kept me very engaged with the chaotic mess of keeping up with everything. I'd love to have a short sprint as in the Overcooked series, just as a cherry on top. 
Great work overall, lovely project.

Very nice graphics visually, but there was too much going on with them to be really clear, I had to get used to it, to see things clearly gameplay-wise. Nice feedback of the actions, although it was also confusing at first so I had to get a grasp on rewinding, and how it worked exactly. Gameplay while pretty simple it was very well done. It felt like doing a lot of busy work to be honest, but I guess it's the way the game is supposed to play out. My bigest problem with the game, that it was confusing at first, the lack of some sort of tutorial was probbably the reason. Overall the game is enjoyable so don't get me wrong, I'm just more used to pointing out the negatives ;P
One thing I would like to see added would be a some kind of sprint button. Maybe also the customers could summon me with some kind of bell before they rage quit and throw the movie on the floor.
Also there was one time that a customer wanted to pay while standing between romance and action shelves, and they just rage quit after a while, but well, I guess it represents real life customers pretty accurate, so... "it's not a bug, it's a feature".

But... The game is quite fun, very well made and present a very nice spin on the jam theme.
Keep up the good work.
