It's Chara's story.. being reenaacted by monsters on the surface. And the locked door to the Underground is right there at the bottom of town, radiating creepy Gaster music.

And the date is appatently 202X now. And Kris has grown taller.

The Barrier has already been broken. That happened at the end of Undertale.

The question now is whether the No Mercy ending is also cannon too.

Gaster may have created an alternate dimension. Alphys searched for dimensions where The Barrier didn't exist as an attempt to bypass it, and it makes sense for Gaster to try the game. The Core was his mad science HQ, and he built the very time/space portal he fell into. So perhaps Gaster either found, or created, Deltarune.

But he'd have to break the Barrier first, in order to do this.

Deltarune might be a dark project, but I don't think it's THE Darkest Experiment.
