Has it just been too long since I tried the game or are these spelling and grammar errors in Melvin's route recent changes?
"You're mistakened. I really liked you too girl." incredibly awkward, and even mistaken wouldn't really make sense in the context. Did they mean "You were a mistake." Or "Hiring you was a mistake, I really liked you too."?
"Then you went ahead and did something like that on my fine establishment?" well for one, Melvin calling his tiny dirty pub a fine establishment in the first place is a joke, but the grammar isn't good either. Something like "Then you go ahead and pull something like this in my establishment?" flows much better.
A few lines that are mostly okay, then "Not to mention the 1000 zel that I lost yerday." Obvious misspelling.
Most of a blowjob sex scene later "But it looks very artistic if I can say so myself." Technically correct, but no native English speaker would ever say it like that. "But it looks very artistic if I do say so myself." Although personally I'd go a step further with "Though I must say the look suits you very well." As its a bit more effective as a demeaning backhanded compliment I think.
A few more lines okay lines, then "(I can feel it on my entire throat)" which in the context I think was meant to be more like "(My mouth is filled to the brim.)"
I could go on but I think this is already too long as it is. I really hope they at least get someone with at least a solid grasp of spoken English to do a final pass of editing before any kind of final release.
