A small observation, your pc will block the game from running.Just ignore the warning and go for it

Seems to be a direct sequel to Undertale!Undertale 2 announced baby!(Obviously Deltarune is not the full game, just a freaking big demo)

Something that is "Far from complete".

Yeah, just wait until its close to complete...

We'll have to return in 24 hours to find out what it is.

Looks cool. So far most of his teases like this is just adding something minor to Undertale. It will be interesting if he is actually teasing a new game though.

Toby Fox is just retweeting the @Undertale Twitter so it's most likely another project connected to Undertale.

"For those who completed UNDERTALE it's really important that you check @UNDERTALE 24 hours from now. 

I want to make something new, and it all begins with your feedback.

A Windows PC/MacOSX PC is needed."

Just hope that means Undertale 2 or a new game from him isnt that far away, since this is looking less and less like an official new game reveal.

Undertale 2 hype.

Time to get spoopy.

Wonder what is going on, Deltarune is an anagram of Undertale
