I hate that I didn't have time during the game jam to implement the solution to the contrast thing you have mentioned. There are lots of comments about that, and you are also right.
There aren't any limitations about attacking, but we'll extend the offensive abilities of the player character with skills and certain character-specific passive abilities. Currently, the dodge feels more fun as you have mentioned since there isn't any variety in the attacking of the player character.
Thank you for playing the game and giving us feedback, I appreciate it!
