could you make another outfit that can make you look normal to people
I had that idea in the back of my head for a while, but I didn't bother implementing that just yet. Once the faction system is in and I add more factions, diguises and bribing will be a thing.
weapons like stronger and faster attacks
This is already partialy in the game. Dragunov rifle for example has a large bonus to accuracy, so you almost never miss even with bad stats. Knives attack much faster than other weapons and so do automatic weapons. Not all weapons have these bonuses yet, but I will get to that eventualy.
Demon Dragon could be a few different things, but I think of fire, wind, or water
Mutations will be more or less "realistic". These will change you physicaly in a way that makes sence, so there will be multiple animalistic mutations and other mutations like different skin color or extra limbs, eyes and stuff like that. Wind, fire and elemtal powers like that are reserved for "blood powers" you get from joining the church and Mr. White in the future.
Could you make a mutagen for the unlimited upgrade mutation so that it isn't random
Mutations will get an overhaul in the future. Once I add more mutation types, you will have some kind of way to choose from them so they won't be entirely random. I'm not fully decided how that's going to work just yet, but it is planned.
And will people be romanceable when you get older, like George and Helena,
George and helena will be the main romance options. I will be adding few more romanceable characters in the future, but you will only be able to romance other kids your age or certain younger NPCs.
could you make certain people not talk to because of your morality?
Morality will mainly affect the way you talk to people and your actions in certain events. In the future, I will be removing large portion of choices from events and your character will respond automaticaly depending on your morality. People will never treat you differently depending on your morality, but they will respond to your previous actions. If you had low morality and you did something bad to them, they will remember that. If you have low morality and you talk to someone you never met before, they will treat you nicely since they have no idea that you are evil.
