Painting all screen kind game

[porzioev]

Hello everyone, I don't even know how to look for it in the forum, so I'm forced to disturb you.

The game I'm looking for was probably like
"Splash" "crush roller" "snake"
but it was on CGA graphics, a small square was commanded which drew straight lines on the screen and as soon as a perimeter was closed, it filled up. You had to avoid being hit while drawing these lines from small squares that freely bounced around the screen. The aim was to fill the entire screen.
Can you tell me how to search for this game, what category or type of game it is, or how to find a similar remake?

Thank you.

PS I tried to draw what I remember...

Must be a QIX variant, like Xonix.

There is also a DOS clone of QIX called KIX.
