Erwin is a sliding puzzle played on the six faces of a cube, a unique 3D experience with spatial audio and holographic depth effects. Swipe to slide and merge tiles, or swipe the background to rotate the cube and work the other sides. Tiles have a value that doubles when they merge, and each merge adds to your score. Play long enough and quantum effects begin to appear: some tiles are in superposition, alternating between two values, some entangled and move together, and some even teleport. Play together with friends via Game Center Multiplayer: take turns on a shared cube, watch each other's moves in real time, and climb the cooperative leaderboard. Universal purchase with Family sharing: pay once, and play Erwin on iPhone, iPad, and Mac, with up to six family members. Erwin respects your privacy and your wallet. This is an app I wanted for myself without compromise or dark patterns: pay once and it's yours, on all your devices, with no ads, no nagging in-app purchases, no tracking, no profiling.
