I read all the comments, and personally, I guess I'm alone in the fact that I think grid movement is...well...super basic? I guess free-movement is easier to do in Unity since the engine is able to do it for you, but moving along an XY grid just sounds like a coder's first project. What exactly is the issue? Is there a mystery thing I'm not conceptualizing here? This concept is as old as chess and checkers...if not, thousands of years older.

Also, what's wrong with using world units? If your pixels per unit is 32, and a sprite tile is 32x32, your world unit should be the same as a grid tile, no? Am I missing something here too? Heck, I'd use both at the same time, probably.

I want to point out I'm well aware I sound like I'm full of myself, I just suck at filtering myself. I've not been in the shoes of having trouble as a programmer -- I'm in the exact opposite sinking ship of having zero motivation and creativity, but can solve any problem you throw at me.
