Ought to I hold my recreation easy or add skins and different issues?

I'm about to do an entire redesign / replace of my recreation (Goal Fury) and I used to be questioning if I ought to add skins and customization outlets or one thing else? Will that make it higher or worse? What are your preferences for easy video games like this?

A gameplay video is obtainable to see what it appears like proper now 🙂

I'm simply attempting to keep away from multiplayer or issues like that as a result of it's actually difficult to handle as an indie developer with out income lol

Thanks a lot in your suggestions.
