Great art and a unique concept, but you have some implementation issues.
IMO, I think your game is too complicated for a game jam game. Most of the time, people are only expecting to play maybe 5-10 minutes on your game, and if it takes more than 5 minutes to understand the instructions, it’s hard to get players. Also, I’d recommend taking the instructions you typed out below and putting them on your itch.io game page, that way others can easily read them in the future.
The game mechanics work fine, for the most part, I just found an issue with dragging a bottle across to the customer and accidentally having it go into a machine. For the customers, the orders were way too complicated, even the first one. You need to ease into difficulty. The first order had 5 different components and I couldn’t keep tabs on them. Unfortunately, he became dust :(.
Now, for the good. The art is really solid. The customers look great and the machinery is crisp. The actual gameplay mechanics work fine as well. This is all good news as you have a lot of the hard parts done well! I think if you simplified the mechanics and had a smoother difficulty curve, it’d make the game more accessible.
Keep up the good work!
