How to make the particles on a Particle System Square?

Hi JonWag!

Create a square in an image editor and export it in png/jpeg (size doesn't really matter).

Click on your particle system, in the inspector, go in the "Particle System" tab and then the "renderer" tab and select another material (the square you just put in your assets folder!). By default, the particle Material's shape is "round".

You can just assign Rendered > Material to None . it will emit a squares by default.
