You may trust this as being true. This is the real deal! There are no advertisements or in-app purchases, and the gameplay is identical to the original Infinite Mario Bros.

It's Grayson Howell, of course. Jan 16, 2021⭐⭐⭐⭐⭐

I was afraid it was a fake or simply a chrome background, but it's the genuine deal.
