Freshly Frosted (2022)

A hint puts a small piece of the correct conveyor route in place, giving your doughnut-production puzzle an anchor. The rest of the belt and the order of toppings remain yours to arrange. I like it for readable, cheerful routing with a concrete nudge available, though there is only one fixed hint for a level. It may confirm something you already knew, so it cannot always diagnose the particular mistake holding you up.
