// AutoSplit script for Manifold Garden
//
// Written by hatkirby, with help from preshing, Gelly, and darkid.
//
// Automatically starts the timer when a new game is started. You must still
// reset the timer manually between runs.
//
// A split is also triggered after being in one of the ending cutscenes for 1.1
// seconds, since this is when the kaleidoscope appears.
//
// The following options are mutually exclusive:
// - Split on every level change
// - All God Cubes waypoints
// - Zero% waypoints
// - Split based on a configuration file
//
// If you want to customize which levels the autosplitter splits at, create a
// file with a .mg_config extension and put it in the same directory as your
// splits. This file should contain a list of level names, one per line. These
// level names must exactly match the names shown in-game using the
// toggle_beta_message feature.
//
// This should be mostly version-independent, but it works best on 1.0.0.14704
// (Steam "Speedrunning Branch").
//
