I'm making a 2D retro-style pixel game and I'd like to know how big my sprites should be.
I'm not talking about the size of my image files (which I decided to use a 32x32-based artstyle), but the actual size of them once they are in Unity.
Should I keep a 1:1 scale and import all of my usually 32x32 sprites into Unity? Is there a special scale up or down process I need to do before or after import them?
I'm saying this because when I'm working with HUD elements, they are drastically really big compared to my tiny sprites, so I'm worried if this could affect implementing something like RigidBody or collisions, and I should indeed scale up my sprites, or if this is normal and I'm being paranoic.
I'll append an image showing my concern.
BTW, the game looks so far as I wanted to, and it's working well, but right now it's more like a proto, so I'd like to resolve this doubt before continuing. Also, I test this usually in a 1920x1080 resolution, so maybe that's why the HUD looks so big.
