Really interesting change. With the change, now we desktop users and lesser gamers can successfully make her escape, whereas it would be really hard to not have the tentacles cum inside her a lot.
Porn games have an interesting relationship with difficulty, because generally the sex scene comes after losing, not winning. I think difficulty doesn't play that much of a factor, besides those that want to experience all a game has to offer or those that want a non-challenging experience. But there are games from the other side, where you're trying to get INTO a sexual scenario instead of OUT of one, which would make difficulty matter a whole lot more.
The resolution change isn't much to think about, more resolution is just better(up to a point). I feel like it's good where it is, though the standard that "gamers" like to propose is 1080p. I say that in quotation marks because I think that opinion doesn't reflect all gamers, much less ones that would be playing this game.
Overall, the game's still really good! Simple but effective in what it's trying to do.
