Not yet, this one is Version 0.4. The full version will be Version 1.0, and if I release any hotfixes to fix bugs etc. then that would be v1.0.1 for example.
If Kosmic restarts development on MR, and I ever need to come back to colour in newly-made scenes, then those kind of updates would be v1.1 etc.
For me, X.Y.Z = (Release).(Update).(Hotfix).
There's just two as far as I know -
Colormod, and the
JoeTermin mod. That one reinstates some unused content like struggle animations, and also adds some cheat options to the game.
You can hold the Down arrow key to keep the scene going, and you can set up a macro for this so you don't have to physically do that

there are no mods to change the in-game functionality that I know of.
