It's cool to see your project is still coming along, you've been at it for what, a few years? Awesome tenacity!
Regarding the styling of your player character, while I don't think you should change the character just because of complaints, I also admit I was turned off by the style a little bit, mainly because it reminds me of like, iOS or Android games for some reason. Maybe you could like, focus-test a few sketches and see what's appealing? Because of someone doesn't like it, they're likely to speak up, but if people are fine with the style they probably wouldn't say anything and you wouldn't get that feedback unless you sought it out.
