I have some suggestions to add.
-Add mercy system like give players item merfy and it has cooldown when they use it add to scoreboard and when scoreboard full the enemy they fight becomes passive.
Other enemies should be harder to spare.

-Give enemy attacks a pattern of atacking. Like undyne shoots a spear under you. Omega flowey has explosive bombs and flytrap traps.
