I not know if you accept ideas in here for improve your game,anyway whatever idea can be talking with your patreons,soo i will give you a few bc your game like me and you can ignore me or not,your choice.
1.It should be great if you in a future add that when you kill zombies from villages or cities then survivors can back and you can talk with them,get secondary missions from them,interactions with npcs like drink or get drunk in a bar, sex events like this ones of gallery or even get chance that some of they (not how enemies) can grab you and rape you and trigger sex scenes,trick you,ambushed you.
2. It should be great if your fill the houses with beds,wardroves,tv etc because actually all houses in the villague look empty (i know that it is bc this game is in beta but i need tell you anyway),not even have beds,it not look real that some survivors lived in there.
3. Add more traps,no bears traps,i mean sexuals ones that trap you,alert enemies and they can trigger x h scenes or capture you.
4.Add survivors enemies that want capture you for traps or when you hp reach zero for have you how sex slave.
5. If you hp reach 0 you not die,you will have a special H scene of game over like this ones from gallery and survivors will remove your gear (you will need recover them with x choices that you will have),if a zombie beat you with your hp in zero then they after rape you in the H special scene they will drag you to his nest for breed and you will need escape.
6.You can add others monsters because the virus,you can add other humanoid or non-humanoid monsters that mutated because the virus,tentacles,parasites like this ones from the movie of *Alien* etc.
7. Enemies no human can have his traps too like tentacles trap in the floor or wall,holes in the wall or ground,quicksand etc, robotic traps or other types that were left there and some zombie creatures with enough intelligence take advantage of them etc.
8. Add more cities and villagues with npcs ,or zombies that you need kill and when you kill them in x mission then the city or villague turn in a safe city,villague/city with survivors.
9. Add system where your choices/talking choices can give you submissive or dominant experience for increase levels,and npcs,they treat you in a different way, for example, apart from the npcs who try to grab you and rape you/sex events, there will be more that try to force you or rape you or trick you, or make you a sex slave if you are submissive.
10. Pregnancy system,you can have x chance of get pregnant amd give birth a small monster or a children,monsters can birth in whatever place and human you need go to x place and pay soo they help you and take carefull from your children that you can see??,i dont know,anyway you not want be in pregnant condition because this has debuffs, soo you will go to this x place soo guys help you to give birth human babies ( insert some scene of birth).
11.Add slave clothes,bdsm clothes that you will wear if you get capture for human npcs or enemies,and a night,morning,afternoon inside from game,works in cities for get money like work in a whorehouse how whore,or work in other place like a bar etc and you need sleep in a INN or bed to spend the night,the night is more hard with strong enemies and more perverts npcs (Remember to illuminate the areas so that the game is not too dark)
12.Add cum in the skin of the caracther after the sex,in the specific part of couse,you can wash this with item or in a shower.
13. Add female and futa enemies and npcs,bc lesbian and transexuals exist and ofc can turn in zombies,enemies,all cant be only males.
