I did Worms -> heal with potion -> slimes -> goblins. When Goblin attacked, I kept getting "Earthworm used Earthquake", and when I attacked the Goblin it was referred to as a slime. Thought you might wanna be aware of that!
Overall though pretty charming and cute. Like the slime sprite. Good stuff! I am not a fan of gbc's assembly so lots of power to you for making this :)
