I'm gonna count both chapters in my review.

As I said in my Undertale review I honestly think Deltarune is a much funner gaming experience, it doesn't "live up" to the absolute monolith that is Undertale but to me it's better on everypoint, character writing, gameplay, pixel art and humor...

I think the fact we get to spend more time with the characters helps with creating an actual attachment to them, I am genuinely attached to Kris, Susie, Ralsei and all the characters that are pretty much always by your side during both chapters, I even like Berdly now !!
