@Vini I did. Two of them were pretty obvious, but the third is only available once you find the location of the thing that they're for. If you're having trouble finding said location, backtrack. Think of everywhere you've been. I just happened to try to back at just the right spot and found it easily, so that was nice.
Nope, that's just Kris/Chara revealing its merciless self. Seems like Deltarune is a prequel, so Chara has to be a killer no matter what. I've started a discussion thread in OT btw, to keep this activity thread from getting too long.
I still haven't beaten it ;-;
I got past the chaos bomb, but whenever I do, I lose after 2 more rounds. I watched a video and apparently I was like 1 round away from beating him. >.< I gave up, though. I don't have the determination. I haven't beaten Sans in Undertale either.
