*highscore is correct, but *initials is not. It means "the value that <initials>
points to", but you want "pointer to initials" to print a string, i.e. without
the "*".
Also, to want to print a string (in C; array of char:s) the correct printf
directive is "%s".

Just curious: why not ngetchx()?

Not strictly necessary since the function doesn't return any value and since the
function is already done anyway.

Char was right from the beginning, plus it holds 4 characters: 3+zero
termination.
Change to:
static char initials[4] = {0,0,0,0};
