DotSpinKoru

A letter sequence training application themed around halftone dot density control. Players select from three difficulty levels: Beginner with 6 circle letters and a 4-step sequence, Intermediate with 10 letters and 6 steps, and Expert with 14 letters and 8 steps. During the preview phase, letters arranged in a circular formation light up one by one to reveal the target sequence. Players then tap letters in the exact recalled order with three attempts allowed per round. The dark-themed interface features animated floating dot particles, pulsing orbital decorations, and gradient-styled buttons with halftone texture overlays. Victory triggers a full-screen confetti explosion with expanding ring animations, while the achievement system tracks ten unique milestones including win streaks, difficulty conquests, and score accumulation. Game history records every session with accuracy, timing, and difficulty breakdown statistics.
