same as 2sheep that if he can move while the selection mode, its extremely frustrating, got him and my 2nd attempt but there was indeed some attacks that were very rng in nature like the ghost copies and the laser beam. the other one i've seen looked rather fair however (the bullet hell ones, the chase and the heatseeker missile type bullets. a good amount of variety however ! only if you added frames to anticipate the attacks, it would be more fair. also, unsure what caused that but i beat him while he had 23 hp. maybe it doesn't go to 0 on death ? the theme was a bit mundane in its use, but outside of that it feels it was a good exercice at boss behaviour pattern. hopefully itll help you in future projects ! :)
