Kana Bubble

Kana Bubble is a casual educational game that helps learners practice Hiragana and Katakana by turning study into a simple matching challenge. The gameplay places fixed bubbles along the screen edges and rising, draggable bubbles in the center; each moving bubble shows a character in one script (for example Romaji) and must be dropped onto the fixed bubble that displays the matching character in another script (Hiragana or Katakana). Kana Bubble makes repeated recognition practice feel like a short, interactive mini-game, offering immediate feedback on mistakes and a compact way to build kana recall for beginners and casual learners.
