You really should reconsider, adding that will get more people to pay for and download your game, or even making a version for free. You will gain more supporters that way, by adding certain things like player customization for those that don't wanna play as a dude and releasing a version for free, so people don't waste their money. There's been several people in the comments that were unhappy and even one person that paid for the game twice and is unable to play it. If you keep going at this rate and not responding to everyone supporting your game, you'll end up with people wanting refunds or you'll end up getting kicked off of itch.io from being reported a bunch. Overpricing your game and not listening to the people actually wasting their hard earned money is an extremely bad idea.
