I know a lot of people have been asking for more PICO NIGHT PUNKIN' content, but I currently have no plans to revisit the game. However, I've made the game completely open source for anyone to mod, with full documentation on how to go about doing so (provided you understand PICO-8) Here's a link to the game's github page.
Lots of talented people have already made mods of their own, and there's some that are still in development. I'm going to showcase a few of my favourites, however you can look through them all by scrolling through this thread on the Lexaloffle BBS.
VS Ninja Cat
by cubee
One of the first mods ever made, based off the creator's fantastic 2D sidescroller Ninja Cat.
Some mods didn't create their own game over cart, so if you die in this mod you'll have to refresh the page.
Dadbattle B-Side
by jo560hs
The first of many mods by the incredible jo560hs. A perfect recreation of the Dadbattle B-Side!
They've created a custom main menu and gameover cart that links all of their mods together, however I will still be linking to their individual carts separately below :)
Kaio-ken VS Shaggy
by jo560hs
This mod has the unique 6-key control scheme from the VS Shaggy mod, controlled with S,D,F,⬅️,⬇️,➡️.
Forest Funkin'
by jo560hs
Play against Meat Boy with a PICO-8 cover of Forest Funk!
Roses B-Side
by jo560hs
Another perfect B-Side recreation with Roses!
Trollface Demake (WIP)
by evman2k
DISCLAIMER: THIS MOD IS NOT FINISHED!!!
This is a work-in-progress demake. If you want to keep tabs on the progress, include the thread on your blog feed on the lexaloffle website, or check back every so often!
Blammed B-Side
by jo560hs
This was actually released the day after making this post so I've updated it to include this fantastic new mod :)
If you enjoy any of the mods in the thread, give them a star on the lexaloffle website! If you want to get into modding the game for yourself, check the github and feel free to message me on newgrounds if you need some help :)
