This thing was kind of a nightmare to code due to the fact that the modding API currently does not support hooking/overloading non-state public functions which meant I had to create this system for detecting if a entity is a enemy that can be hurt/destroyed and adding every single existing enemy and boss in the game to it by hand, this has two technical drawbacks:

All hyper forms cannot drown and have additional visual effects that make them distinct from their super forms like brighter palettes and flickering afterimages. To active a hyper form, transform into a super state then press the 'Z' button. Also of note is Hyper Knuckles has received multiple buffs when compared to his original version he now retains horizontal speed when initiating a glide as well as breaking item boxes when hitting walls at high speeds along with badniks. HYPERMANIA is a mod for the Sonic Mania decomp that - you guessed it - adds hyper forms to the game! but unlike past mods that tried to do the same this one is mostly accurate to their S3&K counterparts, with code based directly on AIR this means that Sonic retains his Hyper Flash and 7-color palette cycle, Tails gets his Super Flickies back and so forth. The wait is for a fully-featured Mania hyper forms mod is finally over! (if you ignore Mighty and Ray hahaha) Please take caution if you suffer from epilepsy or any other similar disorders WARNING: This mod contains flashing lights.
