Thank you so much, left a comment on your game too! Can you elaborate on what you mean regarding Duck & Cover? I'd love to hear your feedback!
It might have been me being lucky, but by using Duck & Cover I negated every action the slime used against me (without needing to click on stars). The same move sometimes deals damage, and after couple of exchanges the slime got tired and I won the battle without having to interact with the enemy actions.
