SANS information, though
Undertale’screator Toby Fox is teasing something big for tomorrow. In a very vague Tweet, the indie dev has told users that have finished the game to return to theofficialUndertaleTwitteraccount after 24 hours. It seems he is working on a new game and is looking for feedback from all fans.
If you’d like to participate in whatever he is planning, you’ll need a PC or Mac computer. My guess is it will be a survey linked to a video, but it could even be a playable demo for Steam owners ofUndertale. We’ll just have to wait and see.

For those who completed UNDERTALE it’s really important that you check@UNDERTALE24 hours from now.
I want to make something new, and it all begins with your feedback.
