It's also in the menu mod, for people who like to load maps that way.
Some things to note are, there are always two pathways to get from color to color, a low road and a high road. You should never feel "punished" for losing the high road, as the low road will also get you to your destination.
Also, there is currently no spawn point, so you will automatically start by dying... So press X to wake yourself up. ALSO, if you go into editor mode (press 9 or esc) and go to a new location, then go back into rabbot mode (press 8 or click on rabbot) that will be a "temporary" spawn point, and pressing L will take you back to that spot. This level has some difficult parkour, and that is one good way to retry those sections.
Please let me know what you think, and hopefully I'll be pushing more updates soon!
