Joyful Gameplay changes and additions Mod

Joyful Gameplay changes and additions mod, or simply known as Prüf's mod, is the first known LISA mod released to public. It was released on the 20th of February and can be found here, in this Steam thread.

Features

 * Buddy can combo!
 * Gary the hot memes!
 * Pain mode!
 * Unreasonable difficulty!
 * Boss rush!
 * More shit!

Influence and Legacy
This mod influenced a small boom of LISA mods, particularly the Joyful, but with an actual party mod and Hell Mode Remix. Later, it was included in the Arkantos mod. The mod itself became a base for the next two aforementioned Joyful mods, Hell Mode Remix and Arkantos mod.

Content
Most of the mod's content isn't so obvious and gameplay-changing (sans Pain mode and Buddy's combo), but it does add some secrets, for example, a fight against Bane if you fall off a certain cliff in Crossroads 1. It also has some minor pain mode additions, like Rich the joy mutant and a Barrel Bro, which influenced the creation of the Hell Mode Remix mod.
