Looks great, but felt really unfair. I had no time to react to the telegraphed red circles, so it felt like the best strategy was to stand close by, getting pushed by him (so I got the standing still bonus) and spamming while hoping the RNG doesn't make him do the hulk smash attack. I did manage to beat him after a few tries, I wish there was a clearer win state though.
I think the standing still = more damage mechanic is really interesting, would be fun to see how giving more reaction time and other improvements (maybe giving the player a dash?) could benefit the game.
