Thank you for playing and liking the game ! Yeah, definitely planned a lot more effects at the beginning, criticals, dodges, defense, etc. But as I try to create the game, I realized that each effects takes a lot more time than I anticipated. I opted to go with the damage and heal as I try to make the rest of the game playable and readable (and also bug free).
Again, thank you for the kind words, they mean a lot to me : )
