So is the only way to beat Everhood 2...

Is to just quit and delete the game? Seems like it's reverse Undertale to the ultimate conclusion. Do everything til there is nothing left. The hilbert hotel as very limited amount of adventures and the challenges are just the same thing over and over again so it seems you'll run out quite quickly. I call it reverse Undertale as in that game The genocide route ending is pretty much that but in Everhood 2 that seems to be the good thing to do.
