Yeppers. It's funny, because UT lead me to design a variation of a delta rune from that game for a tattoo. Now there's a game flat out called Delta Rune. It's a very good demo of what Toby hopes to do in his first game after Undertale. I'm glad it's set in a different universe so despite seeing familiar faces, the events and behaviors are all new, and the new battle system feels great.

I'm playing it through a second time now (since it's only a 2-4 hour demo) and it actually convinced my partner to give Undertale a chance, so it gets a thumbs-up from me.
