Champion of Venus is an absurd, ridiculous, over-the-top porn game, and honestly, it's not that bad. The story and characters are pretty basic, but it's good fun that revels in it's own absurdity. I also loved the rats.
The art ranges in quality, from pretty good to somewhat lacking, and the actual fetishes here get a bit goofy, to the point that unless you're specifically into it (which for most of these I'm not) it can get kind of gross (the impaling stuff specifically is... yeah). But if you're interested in the genre and willing to look past those elements (or have already embraced them, in which case good for you) for some charming and at times decently funny dumb action (in both senses of the word) then give it a go.

For me, most porn games aren't enjoyable because the majority of them include literal rape or a lust filled adventure of heterosexuality where the only "fetish" is how the female looks. The protagonist of those games are also incredibly unsufferable and are overly aggressive and the girls describe everything that's happening with their voice and that's just.. not how sex is

on the other side of the coin, we have smaller indie porn games that are still lustful adventures, but they're more adventurous when it comes to kinks and fetishes. Some of them are entirely dedicated to those fetishes alone. They tend to be more open and less caring about sexuality and gender, and to me that's where it's at.

Champion of Venus is one of these games that care very little about what's gay or not, what's male or female, and the plot is more of a "how can I feel pleasure today" "what topics can I cover in this chapter" "what haven't I already done?" and I find that incredibly based. The game also features a few jokes that are actually funny because the protagonist is a coomer. Not the desperate "COCKS! COCKS! COCKS!" kind of coomer, but rather a more slow and calm approach to the same vision which is a breath of fresh air.

The game can be very extreme and graphic and I know this will turn a lot of people off, so it's definitely not a game I would recommend to anyone unless they're into/don't mind:
-Vore (although optional, you can tell the author does in fact like "distorted" bodies so you will see quite a bit of body horror)
-Cumflation
-VERY BIG body parts
-Every other thing under the "Mature Content Description"

If you don't mind too much about weird stuff or even see it hot, I do recommend it a lot because it's really good.
