I honestly don't know why the creator or creators of the game decided to make the boss that way, but it is quite difficult, since after passing the walls, it is more difficult to dodge his attacks.
Fyi,Prime will be easy if you manage to adapt on his attack part,such as rings,coinflips,walls,the white beam,and the ulam spiral..also if u still struggle on prime,i could help you tho
alr, i now know how to get prime: hear me out: upgrade two regen chips to +3 and one nadir ring to +3, NOTE: Take a few tries and you will eventually beat prime because he sees your chips and prime thinks its a bad chip until it isnt ordinary.. ITS EXTRAORDINARY.
