I designed this when playing a lot of Map Order Shuffle with Compendium, Lexicon, and pistol starts; I'm not good enough to reliably pistol-start all those maps and wanted some sort of extra lives mechanic, but not the "respawn at the start of the level" kind. Thus, this mod. It should be compatible with just about anything, and I've tested it with a variety of gameplay mods and TCs without issues.
It also has a bunch of configuration options so you can adjust how powerful the effect is, how many times it can trigger, and when (and how much) it refills to your liking.
