The patch was certainly eye-opening. It's not so much a big deal for me as it's a fictional story at the end of the day but the obvious safest thing to do is just play this patch free. This always struck me as a more controversial VN than the rest, and the Lora flashbacks, while she's one of the sexiest characters I've seen, the content of those flashbacks have always had a darker undertone, exploring the darker side of the incest fetish. Honestly, I'm all for it. Patch & all.
I might be way more easy-going than I should be because I've been watching anime ever since before I could hold a pencil correctly, so I've seen lolis sexualized and shouta peckers. I've seen characters like kid Goku with his pecker hanging out in almost every episode of Dragon Ball. So from that standpoint, the content in this patch doesn't offend me or raise red flags for me, but I also got to remember that this ain't Japan, this ain't anime and this is an adult game.
