I've been wanting to make my own line routine, but I'm not too good at
assembler (at least not yet anyways). Would a novice like me actually
understand how a line routine would work? :P

You can just use the _ILine call. from the asm studio help file, the
arguments are:
Call _ILine
B = X coordinate of first point
C = Y coordinate of first point
D = X coordinate of second point
E = Y coordinate of second point
H = Type of line to draw:
0 = Set pixels to light
1 = Set pixels to dark
2 = Reverse pixels (XOR pixels)
for some code:
ld b,X1
ld c, Y1
ld d, X2
ld e,Y2
ld h, linetype
call _ILine
