Hi! This is an epic game, for starts, and the screenshot is totally accurate. You can have a hard mode, an easy mode, a black cube only mode, and a black and grey cube mode.
It is stunning, to me I suppose and sometimes I like everything. The menu screen is really amazing.
ITS AN ARCADE GAME WHAT DO YOU EXPECT!
Just the left and right arrow keys, besides selecting things in the menu
Overall THE BEST ARCADE GAME/ALL
I'm pretty sure this is in the app store as well.
