WatchBlocks 2D Sandbox: A sandbox game… on your wrist

I built WatchBlocks out of pure curiosity more than anything else. I kept wondering… could you actually make a real sandbox game on an Apple Watch? Not just a gimmick, but something you can genuinely play and enjoy. That question turned into a challenge. Working within the limits of watchOS forced me to rethink everything, controls, performance, and even what “fun” looks like on such a small screen. The goal wasn’t to compete with full-scale games, but to create something simple, satisfying, and surprisingly playable in a place you wouldn’t expect. WatchBlocks is the result: a tiny sandbox where you can just build, experiment, and mess around, anytime, anywhere, right on your wrist. Would love to hear what you think, and I’m happy to answer any questions about how it was built!
