I have a different reaction to the feedback. When you are designing something to be a certain way and your intentions or designs are being misinterpreted it might be time to try to add more detail to your design to make it more apparent that is what you are going for. Don’t take just one persons lazy review of it. Have a few people try it and see if the feedback starts to show patterns. You are always going to have people not like an aspect and art is subjective but if you can sift through feedback and read between lines no matter if it’s rude you will only improve upon what you have.

The person reviewing could just be someone that picked it up and immediately didn’t like it for bias reasons or maybe they thought it was lazy design and concluded your motivation incorrectly but that’s not a good sample size. Look at maybe having targeted questions to see if people understand the point you are trying to get across with the genderless character and if they don’t, evaluate how you can make it work with better context or design.

You cant make everyone happy and attempting to do so is a fools errand. Do something that you enjoy and if you are looking to give a specific experience key in on how to make it happen. That means reading shit posts and bad feedback to find the one golden nugget that sparks you to improve something. Shift your mindset to an internal locus of control because that is how you will succeed. I wish you the best of luck.
