/* Klonoa Phantasy Reverie Series Autosplitter Version 1.2.0 (24/03/2023)
Supports Door to Phantomile & Lunatea's Veil (Any%/All Visions/100%)
Supports IGT, including adding the additional time from Chamber of Fun/Horror in KPR2
Splits can be obtained from https://www.speedrun.com/klonoaprs/resources
Script and Remodification by TheDementedSalad, NickPRGreen & Ero
Special thanks to:
Ero - Creation of the vars.helper which made this possible
bmn - Providing a starting point for which classes to check and teaching me some things
Nikoheart & baugliore - Teaching me the basics and spending hours in calls with me to help
NeilLegend - Testing and suggestions for KPRS2 All Visions/100% support */
