Speaking of bugs, there´s one that made it over from the old version to the remastered one.
It´s close to the end of current content, when Lena goes to the shopping mall alone, she has the options to go get another tattoo, shop for clothes or enter the sex shop. After each of those choices you come back to the mall floor and can repeat them.
Here, if you choose to go into the tattoo shop an buy any tattoo, then go back inside, the tattoo you just bought is not blacked out. So you can basically buy the same tattoo 2-3 times until your money runs out. Alternatively, if you bought one tattoo, then re-enter the tattoo shop and choose a different tattoo (or all three if you did not get one earlier in the story) you pay for all of them but only the last one you selected will actually be applied, not the other one or two.
I guess easiest fix here would be to add a black out to ones you bought, or not letting you enter the shop multiple times if you only want Lena to get a single and not multiple tattoos at that one occasion.
