Muto kun is Kawaii
It’s a fun game, I think.
I don’t know much Japanese (approx. N5-4 level), so I’ve only played up to the end of the first case (for which I got a B), but it’s been enjoyable so far with decent word look-up (though only minimal word look-up is absolutely needed to understand the situation or guess correctly). I like how it tells you whether or not you chose correctly. The “tension” mechanic seems a lot like the green bar in the upper-right corner of an Ace Attorney trial.
