Hello! I just finished playing the game. While I did enjoy a good portion of the images, I wanted to say that, as some other commenters mentioned, there are some images included in the game that warrant a content warning somewhere. The 2nd level was a sort of warning in its own right, admittedly, but the last levels had 2 of them being incredibly hardcore, and they did kind of ruin my mood for the ending, which I was anticipating. It's completely fair to expect your audience to be into similar kinks to yours, but I also believe it's fair to warn people ahead of time that, maybe, they're not the target audience for this specific piece.
Otherwise, I have no feedback that wasn't already written in other comments, and, as I said before, a lot of other pictures did have a nice vibe for my personal taste, so I'm still thankful for your hard work here. Thank you for posting, and hope your new game goes well! :D
