hi.
good bye ;)
i just realized that in deltarune soul color in secret boss has something with human souls in undertale. chapter1's jevil is red soul,and frisk also has red soul. also in chapter2,spamton's yellow soul is one previews of frisk,justice soul.
so why you gain hp when your LV is up : you are gaining hp of enemy you killed.
just a random thought i got today but looks cool
i'll post some of my game made in scratch.
