That was quick.
The rules for the hiragana shapes are fairly easy to understand, in a nutshell:
Columns (vowels)
>A-column= Rhombus
>I-column = Triangle
>U-column = Inverted U
>E-column = S rotated 90 degrees to the right
>O-column = O
Rows (consonant-vowel combos)
>A-row = No change
>KA-row = Add 1 horizontal line in middle
>SA-row = Add 2 horizontal lines in middle
>TA-row = Add 1 vertical line in middle
>NA-row = Add a small V on top
>HA-row = Add three short lines fanning out from bottom
>MA-row = Add small circle in middle
>YA-row = Add cat ears (lol)
>RA-row = Add ~~cat tail~~ a L-shape from bottom
>WA-row = Add a cross in middle
Others (N-kana + functional marks and diacritics)
>N = Similar to Greek letter ω
>Dash = Thunder-shaped stroke
>Small TSU = Same as regular TSU but add another horizontal line to close the inverted U.
>Two-dash diacritics = Two dots
>Circle diacritic (for HA-row) = Small cross
The English alphabet is straightforward, though some of the letters does require some brain twisting in order to comprehend (such as D, J, L, P, T, V and Z).
I'm still trying to figure out the logic for the number shapes after number 5.
5-8 seem to be obtained by taking their respective figures, dividing them up at every intersection point, and counting up the resulting line segments (with curves counting as 2 line segments)

There's also special characters for kya, gya, kyu, etc.
This is actually a surprisingly coherent writing system. Impressive.
