Stop making fun of the graphics
It is obvious that whoever made this game did this on purpose because you need to pay a 99 dollar annual fee to be an Apple developer on the AppStore. They made the graphics like this either so low performance early iPhones can use this app or as an app you can use in low Wi-Fi settings. They might also just have bad graphics so people will want to see the gameplay for themselves. I think this developer was a genius because they made a simple easy to make game that is also really fun and attracts people to download it. The developer also could have used better props because unity assets actually has a lot of high quality assets. If they wanted us to think it was a game with good graphics they also probably would have created fake gameplay images so it would look more appealing to the general public. Instead they showcase the bad graphics because they want people to see it and install their game.
