No this isn't Minecraft. This is a clone of it called Latura that's actually rather interesting. Instead of everything being blocks, there are also curves and roundness. Like this hill. I was able to walk up it without even jumping.
I know it doesn't look like much, but it's currently in Alpha right now.
