Update: As it turns out, I’m a moron who wasn’t using Translator++ properly. I didn’t realize that you had to export the project in order to apply the translation. I managed to get a reasonable translation of the game working.
Unfortunately, the game prominently features the kind of inflation that involves popping, which I’m personally not into. The game’s DLsite page briefly mentions it, but I didn’t expect it to be present to an unavoidable degree.
I’ll leave the link up in case anyone else is interested, but I can at least confirm that there’s no issue with using Translator++.
So, I tried making a post on F95Zone asking for someone to translate the game. Unfortunately, that’s been a bust so far. One or two people commented “+1” to bump it, but it looks like no one there is interested.
