This is 3D minesweeper. It works just like normal minesweeper, but in 3 dimensions.
There are 12 mines in total within a 5 by 5 by 5 environment.
Each block holds a value indicating the number of mines within it's 3 by 3 block.
You can press "Front" to move foward a layer and "Back" to move back a layer, which you'll need to see the
entire 3D environment.
Press "Flag" to place down flag and "Color" to mark the grids. Use "Toggle" to select the color you mark the grids with.
