I cannot belive I had to read the words "Piles of Asriels dust" in a GMTK jam game. Truly, the Deltarune brainrot is inescapable. Jokes aside, this game was great! The puzzles were really creative and fun to figure out. As some others have already said here, it might be good if you can proceed without every single possible achievment, especially since some rely on knowledge you might not have (7 human souls, pride flags, etc.).
Still, this was one of my favorites in the jam so far!
