Chain Letter

Combine friend skills to complete your own skill build, and hold back waves of demons within a fixed grid. Clear 4 stages and unlock 31 friend skills to form your own party—then dive into this chaotic battle! In the chaos, you must move quickly within the grid and use your skills to hold the line. Each “friend skill” has its own unique command, and the more you get used to the controls, the more satisfying it feels. Gather different types of skills (summons, rapid strikes, AoE, buffs) create your own combinations, and even if you fail, try again and grow stronger. Defeat the demons that keep surging in, all the way to the end!
