〜 A puzzle experience your fingertips will love. 〜 Thank you for playing OddEvenMerge! In this update, we focused entirely on the "satisfaction" of solving puzzles. ・Feel the "Combo" at your fingertips We have completely redesigned the haptic feedback for when tiles merge. As you hit 1 combo, 2 combos, 3 combos... the sensation in your fingertips changes dynamically. Enjoy the tactile thrill of chains even when playing on silent. ・High-score tiles, evolved When you reach higher numbers, the tiles now glow with a liquid-like aurora effect using MeshGradient. The journey to a high score just got a little more dramatic. ・Clearer and easier to play We’ve refined text sizes and board visibility to reduce eye strain, making it comfortable to play for longer sessions. Perfect for your commute or relaxing before bed. Enjoy a brain workout that feels great to touch!
