Light gun: passing level 190-200

Later I killed the second elite and the boss and got a Mini-Magazine and a Light Book. At the end of the time, the third elite was almost finished off, but I still didn’t have the Eagle’s Eye and the “Execution” upgrade, so I had to turn on the time stop once to take the upgrades. As a result, I was wildly unlucky: I took two dodges in a row (42% dodge) plus “Wind Power”.

Important improvements: in addition to the required ones for the light gun, you must take “Fury”.

Boss room: we enter the time stop once (the boss has two full lives). At 190, the boss Butcher leaves puddles of corrosion, so at the beginning we circle around him, dodging the saw and hook. (I try to hit the boss from the very beginning, losing one health cell to gain Rage. I mentally count down about 7 seconds and touch the boss again to extend the Rage buff).
When the nurses come out, I get close to the Butcher and turn on the time stop + continue to hit in Fury. But after a time stop, the boss is still alive, and the second wave of nurses begins.
▲By the second wave, I let the boss go down and eat one nurse - he heals a little. Then I pull it to the very bottom left corner, and I move to the right and up from it. It turns out: the boss, me and the nurses at a distance. The nurses die before they can get close. The result is a clear victory.

Above I wrote my thoughts on passing level 190. In fact, it differs from 200 only in the final boss.@Jason, config: Commander: Silver Wolf 4 stars, weapon rank 5, necklace/bracers rank 4, armor 2, boots 5. Start: light gun...
