I need a small yet solid prototype that proves the core loop of an idle-adventure game for iPhone and iPad. The camera must stay in a top-down view, and everything on screen should breathe a charming pixel-art vibe. Should consist of a 101x101 map that completely has the fog of war except for the center square. When a tile is opened, it should be one of a few square types to start: grassland, hills, ocean, or town. One would be able to zoom in or out on the maps. Will share a game that has the playstyle that I am looking for with finalist vendors. Prefer something native, but open to something else if it runs fast. Deliver a playable map with touch controls that feel natural in portrait mode. Really just uncovering squares to start. • Pixel-art placeholders sized for Retina screens, with source project files so I can swap in final art later • A short README describing how to open, build, and tweak the project in Xcode or Unity Hub Keep the code tidy and commented; I want to extend this into a full production build if the prototype feels right. When delivering, please send the signed IPA or TestFlight build link plus the complete source so I can review and iterate quickly.
