Kana Bubble is a casual puzzle game that turns kana study into a hands-on matching challenge, helping players learn Hiragana and Katakana through short, repeatable sessions. The core gameplay places fixed bubbles along the screen edges showing one script while moving bubbles rise in the center displaying the same sounds in another script or in Romaji; players drag a moving bubble and drop it onto the fixed bubble they think matches. This simple, touch-driven mechanic makes Kana Bubble a quick way to reinforce recognition and build confidence with kana without long study sessions.
