How do I Change the retro styled template?

At first it was awesome, but now its kind of a hindrance . Is there a way to modify it?

explain yourself. modify it in what way?

There are project settings you can change to adjust various things. A retro style template basically just has the project settings a certain configuration and has some objects already added to the project, like keyboard, mouse,etc.

Modifying it to remove the pixel/ retro effect itself

configuration settings:

sampling: point/linear (point will keep pixels crisp, linear will blend the pixels)

I just figured it out. The problem was actually in the full screen scaling. But thank you so much for your help!
