As an update, this is one of the screenshots of my game so far. Currently the game is only made of UI widgets of transitioning menus. The basic mechanic is not made yet, but it’s good to see the basic UI of one of the more developed screens.

As for learning how to code the mechanic I need, I am following this basic blueprint tutorial series to hopefully figure out what I need.
From this I have come to not consider spray paint, sponges, or art rags as apart of pointillism as they provide too wide of a range compared to a single dot of a pen. What I am going to include is a practice area to have overlying outlines for the player to fill.
