That one's related to Gus! In Day 4, there's a few things you can do that will give you different results. One of them is normally tame, but if you're aiming for Gus, maybe it won't be so tame!
Like on day 8 I want to learn about all the characters powers like I already learnt about Faust power (turning blue whenever he gets spooked), I'm not sure on Rob but I think his power (anytime he sticks out his tongue it makes them horny? Not sure.) I want to learn the rest of the powers of Ed,gus,Hector and Mike. Unless if I'm missing someone who used their powers
