Papyrus: Arrows to move, use a variety of keys to use attacks. And, not seen in the regular Sans vs Frisk, we have the orange soul mode! However, instead of always moving, Chara will always jump (until 0 pressed) due to my poor coding skills! Mercy is NOT for Papyrus. Chara: Arrows to move, down arrow to attack, P for... "mercy".
Papyrus may look like he has an unfair advantage, but he can't dodge forever. Stay DETERMINED.
