If I would judge it strictly as a font, rather than a coding accomplishment (rotation in few bytes), I have to say it doesn't look great. Hard to read and so forth.

Actually, I did this in 122bytes with a different method. :)
I will add that one as a new entry later on today.

This is nothing new really. I have 2x16bit texture coordinates what I step by a 2x8bit vector, the low bytes are on ZP and the high bytes are in XR, YR what I use when reading the pixels.
The texture coordinates of the 1st pixel in each row is stored as data (32bytes).

The "core" of the routine is something like this:

;writing one pixel
lda #0
cpy #8
bcs +
lda (charrom),y
+ cpx #8
bcc +
lda #0
+ and bitmask,x
cmp #1

dest:
rol $3800

;stepping texture coordinates
lda xlo
adc #dx
sta xlo
bcc +
inx
+ lda ylo
adc #dy
sta ylo
bcc +
iny
+

It's getting smaller, I am at 182 bytes now (I just need to flip the last to digits and I win the compo I guess :)) that includes showing the full charset.
I will update the release later.

This entry is outside of compo, as it is too big.
The method allows 0-90 rotation and zooming. I will probably include a version that is <=256b and asks for input parameters.
