So lemme deconstruct something there point by point.
1: That would be making an entirely different game. They wanted to make a cock vore centered game, and built up the way the world works around that feature. If it's not your fetish, or not your focus, then the game just isn't for you.
2: Honestly, most of the cover *is* sized for the crouch to work. Things like the vents or most boxes. Now a crawl might be interesting, but it's also something you wouldn't be able to do with prey.
3: That's... the point. If you *have* to cock vore regular civilians, your mistakes "add up" and make it harder to maneuver and navigate. You aren't supposed to be snagging everyone. You're here for your targets.
4: Irrelevant as the game doesn't let you kill anyone. If you wanna "get rid" of prey without a chance of their cum bag getting found and dragged to a reformer, you have to either hide the bag in an out of the way place... *or* find a partner, because they will stay non-aggressive after being filled.
5: Honestly, this just felt odd of an argument. It takes like four pumps, and you can just hold in. You don't need to constantly fuck to cum. You just have to trigger the cumming animation.
6: Again, refer to point 3. This is intentional to design to be an issue if you're just going after everyone.
7: I would give you credit for this, as rebinding is good... but there is only movement, objective tracker, crouch, sprint, and interact. Not exactly a control heavy game.
And your last note may not be bullet pointed, but why are you playing a fetish furry game if fetish furry content isn't your stuff? Like... just sounds like a bad idea.
