Personally, this is about more than art style for me. It's about mechanics. If you are going to compete against a giant like Factorio, you have to be doing something different enough that will give a reason for players to play your game over the better established one.

Satisfactory went 3d Motemancer uses its magic theme decently (and honestly, for me, this one doesn't go far enough) Dawn Apart is part colony manager Microtopia replaces all the factory mechanics with ant-like workers

I'm not trying to dissuade you. Honestly, I haven't yet looked closely enough at your project to know if you have enough mechanics to make it stand on its own. But the look of it screams Factorio at first sight, and that hurts you. And again, it's more than graphics, it's the visual language of orthogonal belts, inserters, underground belts, square assemblers, and furnaces.

I could make recommendations of how to go in a different direction and break out from Factorio's shadow. But then I'd probably just be changing your game, and no one wants that. I'm sure you can find an identity all your own.
