I'll try to give you a decent answer

There were many sources of inspiration, some of which were:
A cartoony raygun I made to see how fast I could draw and program a weapon
An notebook from like 10 years ago which I used to draw characters in doing random stuff (which is where the style is taken from)
The friend who I based the protagonist on (in both appearance and demeanor lol)
The desire for a cuter doom experience with more sparkles and less blood
The Adventures Of Square
80's action movies (spot all the references lol)
and most importantly, the fact that many people in my local town seem like joyless, hate-filled zombies, and how it'd be cool if it was possible to use electricity and light to drive the misery out of them and help them cheer up

(I know it'd probably just result in them getting annoyed and possibly burned in real life, so don't try it at home)
I do have a few ideas for other mods in this style, so I might be making more at some point. I want to finish polishing this one up first though
I know how you feel, it's almost like people forget that making a female protagonist is an option (unless she's a stripper, in which case it's ok apparently)
I'm more than ok with playing as a dude if it makes sense in the game's plot, or if it's a likeable character, but other than that I'd honestly rather play as a caterpillar in a jumpsuit than John Generic: Space Marine in Space.
@captainj Don't worry about offending people, just make a character you think is cool and sends a good message, and if people have a problem with it then it's up to them whether or not they let if affect them. Look at Bloodstained, for example. It's like Duke Nukem blew a load all over Castlevania

The big gaming studios (and the bigger indie studios) are getting away with all kinds of stuff. If someone is upset about an aspect of your character for a bullshit reason (like "fuck you why is she not a skinny bimbo") then they're obviously either very bored or very sad.
Bottom line, just do what you think will make the world a better place

(within reason of course)
