So as you can see, decent balancing of the game’s difficulty is extremely important and an area to which I have paid absolutely no attention

Man! You can’t move your player diagonally!

Yeah, that’s from Part 7.

It’s not hard to alter though (I did leave it as a challenge ). The simplest way of doing so is by changing this:

if ( downKeyIsBeingPressed )
{
    avatar.moveABit( 0, 1 );
}
else if ( upKeyIsBeingPressed )
{
    avatar.moveABit( 0, -1 );
}
else if ( leftKeyIsBeingPressed )
{
    avatar.moveABit( -1, 0 );
}
else if ( rightKeyIsBeingPressed )
{
    avatar.moveABit( 1, 0 );
}

to this:

if ( downKeyIsBeingPressed )
{
    avatar.moveABit( 0, 1 );
}
else if ( upKeyIsBeingPressed )
{
    avatar.moveABit( 0, -1 );
}
if ( leftKeyIsBeingPressed )
{
    avatar.moveABit( -1, 0 );
}
else if ( rightKeyIsBeingPressed )
{
    avatar.moveABit( 1, 0 );
}

(Check the ifs/else-ifs carefully if you can’t see a change.) There’s more discussion in the comments of Part 7 itself.
