I should learn to read reviews before buying games, probably.
The gameplay itself isn't bad - it's less an idle game and more of a resource management incremental game, which is fine, I like that kind of thing regardless.
The issues, as have been pointed out by others:
1. No saving the game. The first time, I thought I did something wrong and missed a save button. No big deal, I hadn't made it that far, so I just restarted. Then I realized that there was no where to add a save, it simply isn't an option. This is the biggest red flag for me.
2. There's no way to really know what your customers like, and you can't offer multiple products to allow for customization and order changes. You can purchase "extras" that your customers can add to their order, but you have little control over when this happens and you have no idea what extras people are buying. And this isn't randomized as far as I can tell; the drink I made on my first playthrough worked perfectly for my second playthrough as well. This worked for getting me further, faster, but adds a bit of dullness to the game. If your drink is too sweet, it'll tell you, but there is no way to discern what balance customers actually want other than trial and error, which is frustrating.
3. It also seems this game is abandoned. The last update was over two years ago according to the Early Access disclaimer, which I also admittedly did not read before purchasing. I bought the game as part of a bundle and cannot refund it without refunding the other games, which I do like, so I'll be forced to hold on to this game, but otherwise it's 100% a refund for me.

Overall, it's a cute game with a neat concept, executed poorly. You can find other games to scratch the idler/clicker itch elsewhere, and those actually allow you to save your progress.

very fun business game
