To make the game a bit more challenging an less predictable add a little
bit of randomness to the `dy` value. When hitting the right wall add a random
number (one of [-1, 0, 1]) to the `dy` value.
To keep the difficulty level managable limit the dy value to be in the
range from -5 to 5.
Don't use relative imports like `../foo.h` as those depend on the
relative position of both files. Rather than that use imports relative
to the `src` directory, which explicitly is part of the include
directories.
Fix the comment as the comparison checks if the ball is at the right
side of the screen.
Compare the x coordinate of the ball with the horizontal resolution of
the screen, instead of the vertical resolution. On the PinePhone this
does make no difference as we have square 240x240 screen. Change it
anyways to be completely correct.
