Description
Hi HN,I made a small game in Swift to visualize Nurikabe puzzles in 3D, using SceneKit and Metal shaders with some SwiftUI on top for buttons and hints. It's currently available for free in App Store.I've tried generating islands like this a few times before, where the whole board is just one big mesh, but I struggled with the shorelines (especially in corners) and also to make the islands somewhat unique and interesting. This time I got inspired by Oskar Stålbergs "dual grid" approach (https://x.com/OskSta/status/1448248658865049605) which made it a lot easier I think. Happy to provide more details if anyone is interested.Anyway, I would love to get some feedback on the game: Is it understandable? Too easy or hard? What should I focus on to improve it? Thanks!

Could you build this?
Partial While Nurikabe rules and standard grid UI can be vibe-coded, procedurally generating guaranteed unique-solution boards and writing custom 3D Metal shaders and SceneKit pipelines require domain graphics and algorithmic tuning.
What it would actually take: A full version requires a Swift/SwiftUI application utilizing SceneKit and custom Metal shaders for real-time procedural mesh and ocean rendering. The main technical hurdle is procedural generation: generating valid, aesthetically pleasing Nurikabe puzzles of varying difficulties that have strictly unique logical solutions without guessing, combined with smooth 3D GPU rendering pipelines.
