There weren't a lot of good secrets. Also, there were some grammar mistakes and the San's room trick didn't work for me, and write something about Gaster. Please add more secrets and take out the constant ads for me to give it five stars.

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.

If it was updated with more secrets, it would be worth keeping. It only has about 7, so it's not worth the phone space. You're better off Googling what you want to know.

There are just a fraction of secrets here. Tell us about the genocide run if you spare a certain monster. Or the no mercy crerpypasta. Or the audio clip ABC123

Some wrong grammar and spelling here and there. Needs A LOT more stuff added.

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 )

I liked it but when I got to serious mode i couldn't scroll down D;

Mal. S. Mar 12, 2016     

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.

It doesn't give you many secrets

The sad fact this is the only undertale thing on the play store so if u make something better like some live undertale wallpapers you would be brilliant.

I'm kinda good but there's WAY MORE SECRETS​!! like:1 kill toriel then go back to were you start then you see toriel beside flowers when you talk to here she said the same as asriel when you compleat the game and go back.

Sem. e. Jan 23, 2016     

The facts are fine, but there're only very few facts to read.

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

Mar. P. Jul 29, 2016

You show in the picture undertale secrets san's secret yes in his workshop you will see a broken time machine a badge a photo and a blueprint actually if you know earthbound in the picture it says that sans is in the picture with three human he looks happy actually the one boy in earthbound was sans is the boy that wears a cap if you can identify sans bone hands are the same at the boy at the earthbound cause the boy in earthbound is also hiding his hand so sans is the boy on earthbound(sorry I don't know the name of the boy but you can search it in Google);) but there'should more you need to know about sans from know this is my explanation I hope it helps you in playing undertale
