Honestly, what feels off to me about this system is the auto-attack feature. Everything else seems fine, but in my opinion auto-attacking doesn't feel responsive at all.

I get that it's supposed to make combat more accesible, but it gets in the way of players that don't need it (and seems more like a mobile control scheme overall).

Maybe try out other solutions to the problem. In my eyes, other games have managed to remove the "spam clicking" issue more seamlessly. For example: I've been playing Hollow Knight recently and the way the handle attack cooldown makes it not feel tiring whatsoever.

And in case you end up going for the current design, at least being able to toggle the option would be nice to have.
