It’s called Influent and I first released it in 2014. Added a bunch of other languages since but it all started with Japanese. Shout out to Shashingo as well!

So I made a Japanese learning game on steam and I get hit with negative reviews all the time because it doesn’t have enough real Japanese words in it. /facepalm

Edit: Game name is Influent, heavily focused on vocabulary building.

DarkAudacity ftw!
