What mobile game is the store clerk playing in episode 10 of 13 Reasons Why?

In Season 1 Episode 10 of Netflix's 13 Reasons Why, you can see a store clerk playing a game on his cell phone around the 11:20 mark.

From the short clip, it seemed like a top-down MOBA made for mobile phones.

What game is he playing, if it's a real game at all?

My conclusion from looking at the game in the image: that is likely to not be a real game.

From where the store clerk is tapping, it doesn't look like he has any goal in particular that he is trying to do with the game. I don't see any buttons or avatar either that he could be tapping or controlling.

My guess would be that this "game" is a placebo or something to make it seem the clerk is playing a game or being busy on his phone.

Hope this helped! Should I get any tips I will update my response.
