Adds a new Boss Rush gamemode. Fight every boss level in sequence, then do it again but harder. Each lap increases difficulty using radiance, which can be tuned in the mod config.
Hardcore mode will restart you back to the very beginning if you die, so be careful.
Rush Stats
You can now customize the level route in the mod's files. ULTRAKILL/BepInEx/config/BossRush/LevelChain.json
LevelFrom - is the level the player is leaving
LevelTo - the level the player will enter after going into the final pit
PitTargetFilter - ("" for no filter) will filter the pit target in cases like 6-2 where the player could possibly enter the pit for P-2. In this specific example the filter would be "Intermission2" since you enter the 2nd intermission after being Gabriel 2
The very first LevelChain LevelFrom field in the file will be considered the first level and Boss Rush will load it when you enter Boss Rush mode. To establish a loop make sure the last LevelTo is matching the first LevelFrom field.
if your LevelChain.json file becomes corrupt it will be re-written by BossRush to the default chain.
