PlusMinusBakery

An independent, offline iOS 15.0-targeted SwiftUI arithmetic puzzle game. Five chapters contain 80 verified recipes: select single-use signed ingredient cards, keep every intermediate bowl value within capacity, fulfill starred conditions and reserve cards for paired orders. The order counter, ingredient drawer, per-order baking receipt that survives relaunch, recipe book, free-knead practice, layered hints and first-run lesson form a complete playable loop. Simplified Chinese and English, three appearance choices, separate sound/haptics controls and a scrollable kitchen guide are included.
