Making Slendytubbies 3 DLC Game on Roblox

[Asia]

I've been working on a slendytubbies survival game for a bit and i just want some questions on what i could possibly add,
I made newborn ai and stuff,
It looks real cool rn and the main point of the game is your the guardian and you can equip accessories cosmetics in the main menu,
But the big part is the monsters, you can search for these "custards" around the map and when you find one, you can consume it, you have a chance to become tinky winky or any other powerful infecteds, or you become a newborn
if by chance you do become any powerful infected tubby every other custard will stop existing completetly untill you die or your time expires. (you get 10 minutes as an infected or infinite as a newborn)
how you can kill these infecteds is searching for guns around the map or talking to sgt miles about buying guns,

The infecteds get abillities that derive from themselves, eg tinky winky can grab you and rip your head off. or laa laa rushing you
You get tubbycoins by killing teletubbies/infecteds or just finding them on the map.
what should i add?

This is really cool. I don't have any suggestions at the moment but if I ever think of something I'll let you know.
