I can’t believe they posted a Tetris clone to begin with.

Tetris is a game where the perfection is taken away from you. You will only be left with your mistakes, mistakes that haunt you and which keep piling up when pressure increases and it just keeps happening until you lose. You are left with an imperfect wall.

Also it’s a game from Russia.

So, definitely a metaphor for the Trump administration and the border wall.
