First off, they said nothing about Mettaton EX's quiz. If you type in Toby Fo, a swear, legs, leave it blank, or etc. Mettaton gives responces. Second, if you keep petting lesser dog his neck stretches along the whole screen. Third, if you kill anything in the pacifist route, it doesnt change to genocide, but you have to fight sans. Next, it doesnt explain the names well. If you type in Metta you get the rwspone OH!!! ARE YOU PROMOTING MY BRAND??!? Also if you tpe in frisk fo pacifist it warns you.

I found more secrets such as the gaster people and hard mode it could kid have more content but it's pretty good. Also you didn't mention that you had to walk right in sans' room. And by the way it's been 2 years so it actually is legal( to that random person who said have fun in prison )

The game wouldn't let me scroll down after a point even though there was more to read, and doesn't have much content. Pretty okay other than that.

Z70%
by Z####:

It just needs a bit more perhaps more about Gaster or more hidden rooms like if you find the four hidden flowers in the bridge thing. Other than that pretty good : )

one word response on first look: NYEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEHEH btw add gaster's room, the part when you get in sans and papyrus' house, if u walk between the kitchen and the living room quickly over and over, papyrus will say something different, the "pet lesser dog too much and his neck will grow", translate entry number 17 in hotland, it's in wingding and there is a translation for wingding, seriously just search up on youtube "top ten facts about undertale" and boom, about ten more facts for you
