Yes, official translation is very bad. It's understandable but littered with grammar and spelling errors. Text goes out of boxes sometimes as well. A few examples. As soon as you start a new game, you are hit with "prolouge" for several boxes, misspelling the same word in the same line (scene where they discuss the meaning of sp, point is misspelled), title drop achievement is misspelled, the cut element is spelled as "severe" instead of sever (you can see this one on the steam store page in one of the preview images). And these are just spelling errors. There are plenty of grammar and tense errors. I could probably go into the game right now and talk to any npc and find one. It's like every other line has some mistake in it.
Decensor also looks terrible in some cgs. Artist probably didn't put any effort into the original since it was going to be censored anyway.
