To me the boss just doesn't have any really satisfying attacks which makes it boring. The only really satisfying attack is the 3D sphere at the end... but that's at the end, idk I just didn't find it fun and I was excited to play it
I don't know how you guys can all feel this way about this boss, I don't see a lot of other aiwanna games with good avoidances bosses like this. Yes there are some attacks we have seen used in other avoidance bosses but that really doesn't kill the good boss experience for me because you can't have all the attacks to be completely 100% original.
