Learn Japanese by ponpon is a trivia game designed to help people memorize Japanese words by answering the English questions with the Japanese equivalent. The difference between this game and other language learning games is that users must input the answers manually by typing it in on a custom OSK.

Release notes:

In this update I added a option to randomize the questions, and I included a Karaoke rhythm game. Since this version uses Lua Player Plus by NaNnI & Rinnegatamante, it now features MP4 playback. However the LPP version that I used didn’t have IntraFont which was required for Japanese text input, so I included a option to switch to LuaPlayer Euphoria by Zack in the options menu. It just doesn’t have MP4 playback in that version, but it runs much more stable though.
