Japanese practice
Side projects that have nothing to do with electromagnetic field control. Reading drills and number-sense games for working through hiragana, katakana, and arithmetic in Japanese.
Mental-arithmetic drill with kana number-readings.
Toggle the difficulty axes — scale, irrational numbers, mixed forms, reverse, conversions, chaos — and the angel keeps generating problems that fit. Designed for the part of practice where you stop counting and start feeling the numbers.
Hiragana and katakana fall from the sky. Type them before they hit the wave.
Themed for 夜 (night), 朝 (dawn), or 和紙 (washi paper). Toggle hira/kata, dakuten, digraphs. Chains build a combo bar; missed kana feed the seigaiha-wave danger zone at the bottom of the screen.
