Automation games are really difficult to pull off for a game jam, so congratulations on making the submission!
Unfortunately, the game doughnut did not have long enough to bake in the oven - must be those ordering raw dough eh. Once I worked out how the duplicator worked, it was nifty (very Shapez-esque), but the lack of UI and any information screens really harmed the overall experience. and made it a game of experimentation through confusion and lack of information.
The core idea is there though if you wanted to expand on it, but I would prioritise the UI and the system providing feedback to the player.
