kanatest 0.4.8-4 (arm64 binary) in ubuntu bionic

 Kanatest is a simple hiragana and katakana drill game. It checks your
 knowledge of Japanese kana characters.
 .
 There are three drill modes: hiragana mode (hiragana charset only), katakana
 mode (katakana charset only) and mixed mode (both charsets). The tester shows
 random kana characters and waits until you enter the romaji equivalent in an
 entry field. At the end, statistics are provided.
