i do have an idea, maybe have like a god helmet that isn't op but can pick an effect, look of a helmet, and one of these effects. it would be a pretty good fix if somebody wanted to keep there helmet looking the same but have another effect.
If you mean something like headgear "skins" that players can equip on top of the actual helmets that provide stats, I did consider that. However, I decided against it because it would add a layer of complexity that might not fit well with the casual nature of the game. I try to keep the mechanics simple so it's easy to pick up and learn the basics.
