I like how you made a Halloween themed game! (Even though the play test was a week later lol). It was nice that you made Jack o' Slammer automatically block the player's attacks to make them learn that it's a 'turn-based' game. It was also nice to see that the player has time to react to the punches. I'm not sure if I noticed it during the playtest, but maybe you can gradually increase the difficulty by giving the player less time to react to Jack o' Slammer's punches :)
