I'm sure it's pretty easy but my head is dead tonight and i can't seem to find a solution.
If you have an idea that would be nice.
Basically when you press anywhere you span a box. And there are 4 yellow placeholders.
If the placeholder is overlapping with the box set its instance variable to true.
Once you have 4 "true", the game stops.
For some reason the bool does not come to false when the box is not overlapping the placeholder anymore.
