In general
- Mostly uses the AngleDraw  (Which its sorta complicated to make them all paper-y and flat turning or just being flat.)
- I was originally gonna use a somewhat larger sprite. But instead a smaller one was created (Based on an old lib from MFGG . Net)

Paper Mario
- The palette "Doodle.act" is based on 2 spongebob episodes (FrankenDoodle + Doodle Dimention) and its Game spinoff for the DS (Drawn to life) Hence there's a few hints of doodlebob and franko's drawing of mario
- The Readme File's story segment mentions the current producer (Kensuke Tanabe who doesn't like it to be an RPG after SPM (Ironically turned good but retconned on the lore.) and the former (Ryota Kawade: who formerly worked on the first 3 games as RPGs). Despite the character is supposed to be a love letter to both old and new fans
- There's an Um Jammer Lammy and Henry Stickmin reference in one of the intros. + A Parappa Palette
- There's also a folder that has permission from Infantry00.
-The other pencil in the Disco no winpose is my IRL hand. + Pencilmation reference (before the huge downhill)
In addition: Another Henry Stickmin reference and a Jojo's Bizzare Adventure Reference.

Paper Luigi
-Uses my own paper mario sprites as a base.
-Before the release video came out. Paper Luigi had a lil polish up for a lil special intro against his brother (If hes not in his normal mode)
-One of the winposes is basically Smash 64 (Suggested by someone)

Kammy Koopa
-Her voice clips are basically Kamek's/Magikoopa's Voice Clips pitched down by 10 (Via Audacity and Not taken from the recent Mario Kart Tour voice clips but rather The NSMB series).
While a few others are from: TF2's Merasmus but pitched up by 10 (Also Via Audacity).
-The Giant Block super is a remake old the old one but you have a bit more control to utilize what it should be doing. + Direction Indicator.
-There's some bits of Neo Kamek's Kamek.
-She is the 2nd character to utilize Alessi's Stand attack (Where she turns younger than being elder for a few seconds)

Paper Bowser
-One of his pallettes is one of my Fan characters

-Koopa Troopa

-Dry Bones

-Koopatrol

General
-Instead of the cliché POTS style. A lil more combo-y stuff was implemented akin to lets say... the infamous pocket template
-Most sprites were given color separation (Look it up) during development back in 2019-2020.
-Some of the characters may also have some inspiration from JKS / Koopakingdom.Com's SSBE "Smash Bros Extinction" game.
-

Mario
-The obvious shows its a remake over the Original ErmacWon's version
-Plays like Ryu

Luigi
-Plays almost like Ken

Wario
-Not much i can say here

Waluigi
-Has moves mostly taken from Mr IBZS' and Warioman's Waluigi

Pesky Hammer Bros
-Readme states 3 of the elements were taught by certain other characters
Such as Ryu (Street Fighter), Sub Zero (Mortal Kombat), Terry Bogard and Kyo Kusanagi

That youtuber formerlly knon for being full of Super Mario Recolors.
