It depend. If it's about something with a very simple plot, like this game look like to be, then a basic understanding can be really better than nothing. But if it become a little bit more complex then it become unplayable.JUST ANOTHER MTL RANT. FEEL FREE TO IGNORE.
Another MTL, another crowd of people being happy about being spoonfed actual garbage. I can't understand this "MTL is better than nothing" mentality. I'd rather look up the CG gallery and settle with that instead of downloading dozens upon dozens of Gigs worth of useless media. I mean, I can't even look at the "latest" feed and feel that initial joy when somethings gets my attention anymore.
I really wish for more games being excellently translated. But the process is long and the volunteers very few. Sometime is necessary to simply get what you can get. As the old wisdom say "beggars can't be choosers". Even if sometime i really wish to learn japanese. Not only cause not many titles are properly translated, but cause with all the amazing titles that are waiting out there, when a new game appear in these threads is usually some cheap NTR/futa/gender bending crap.
