I still have some things to say I just didn't want to put every thing into one comment, but before I will clarify some things from the old comment
With a content menu I mean not customizing the hole game just things some People like and others not, like pregnancy you could limit by how many things you can have inside you, and if the player doesn't like it at all he can set it to 0(setting it to low should then disable the ability to earn achievements because it changes the gameplay to much)
And with the metal sounds I have not that much against it, I just saw like you said that someone else didn't like it.
although would need to hear it with normal sounds before I make a final decision. Here you could add a toggle like you did with the muzzle flash in 1.0.4
And with my ideas being too vague... I mean that's what they are supposed to be, I am not going to think a Complete stage when you can then you just say nahhh don't like it.(no offense)
And for the Gangbang I am not giving up that easily. I of course don't know how you made every thing but, Currently enemies have only one h-animation if it would be easy to add more than one you could see a Gangbang animation just as another animation where you check if gangbang compatible enemy is nearby and then chose this animation instant of the normal one.(if that's not possible that I hope that at least some enemies will have more than one animation available, but if the gangbang thing doesn't work I think that's also not happening)
Now to some new points.
I think I have found a bug the big bug (pun intended) in the cave does stuck on an H-animatzion some times,
at the end when it should move to the nest but it does nothing.
And I think the amount of traps on the jungle should be limited maybe depending on the difficulty ?
And definitely be able to change the order of your guns.
I have a sound idea don't know how it would sound but you could add a pussy sound while being fucked to the slap sound which sounds wetter the higher you libido gets.(Similar to the fingering sound)
I think the first half of the Zombie grabber animation a bit to long it would be nice if he would bite you only half as soften but does twice the damage not to hard just a bit to long
Small unity questions.Is there a reason why you save your progress in the game files and not somewhere on the system so that you don't need to replace the file on every update, like Application.persistentDataPath not an expert hope I am not missing something.

And for real that's your first game I am stunned, can't wait to see what stuff you will make with even more Experience in some years
