"arousal=0" is a tactical cheat, the consequences are mostly harmless. I admit I used it a couple of times.Actually, I've been messing around with the console using F12 and there's 2 commands that you can use.
"SugarCube.State.variables.arousalmax = 10000" this one changes the maximum amount of arousal you can have, pretty self explanatory really, 10000 is the default i haven't used these "max" commands yet so i don't know if they reset. Alternatively:
"SugarCube.State.variables.arousal = 0" Sets your arousal to 0
There's so much more commands too, i found out about the console from a previous post, but it barely touched the surface.
You can change virtually anything if you know the correct keywords.
"arousalmax=..." dunno what happens if you change it. I would never touch it in a save I wanna keep.
You really should not encourage noobs messing with stuff you don't understand. That's just CENSORED.
