I really wouldn't recommend this for a total beginner, but it's funny to picture a total newb trying that.

If you don't know any Words, Kanji, or Grammar at all, it would be like running an entire book through google translate (line-by-line) and trying to learn the meaning of each Word and Kanji by repetition while guessing how the Grammar works. It's not so bad if you know a bunch of the words and some Kanjis/Grammar to begin with, by the process of elimination (eliminating the words you already know) you can figure out what the other Kanjis mean, because the game will likely repeat them and you'll learn by context when Google Translate keeps giving the same definition to the same Kanji over and over as you play (same for the words), but the Grammar you'll have to study separately. This will easily turn a 16 hour game into a 160 hour game (perhaps longer).
I don't want to totally knock it though, this approach is fine if you've already studied a bunch and need practice while learning new Words and Kanji at the same time. For a total beginner, you need games that specifically target that market, the Learn Japanese games we talked about last time are perfect.
I found some other ones, one looks decent, the other not so great.
This doesn't look like it's worth $25 the words are too easy, you can learn them in any Japanese beginner book, or Youtube for free. If this game shows up in a bundle for 60 cents, then I'd recommend it.
Learn Japanese is an innovative game where players will learn the Japanese language with minimal effort. Learn Japanese is the fastest way to learn the Japanese language.

This game looks much better to me, but I don't think it's worth $20 I would say $5 is a good full price and bundle price would obviously be best.

If I'm being critical of it though, it replaces Kanji with Hiragana. The Kanji 私 is spelled out as わたし in the game (WATASHI) it means I or Me (depending on context) and 犬 is spelled out as いぬ (INU) it means Dog. Here I'll point out in case anyone will call me out on it, that の (NO) is Grammar, it turns "Me" into "My" so "Watashino Inu" means "My dog" so yeah, my complaint is that it's not teaching you the Kanji that would show up in real Japanese, but to be fair, this is how they teach Japanese children before introducing them to Kanji, they start replacing the words spelled in Hiragana with the actual Kanjis, that replacing part you'll have to do by yourself using a book or Youtube, but as long as you're aware of it, the game looks nice.
