Click the green flag. When [phase #] is a whole number, (not a decimal) click to go to the next phase. Phase description is in the notes. There's 4 phases, 7 including the transition.
Phase 0: Nothing. That's the sound of a loading screen finishing loading Phase 1: Passive. It won't attack. You can back out of the room if you want to. Health: 1 Phase 1.5: Corruption. Basically an intermission. and a "doorway" to phase 2 Phase 2: Annoyed. Attacks are small, but they can do a lot of damage over time. You can still back out of the room if you want to and it will go back to phase 1. Health: 50 Phase 2.5: Going mad. Same as Phase 1.5 but with more disturbing images. Phase 3: Mad. No going back now. This phase can pack a punch and is highly likely you will die here. Disturbing and weird. Health: 250 Phase 3.5: Powering up. Energy flying towards the boss can damage you, other than that, it's yet another transition. Phase 4: Destruction. If the last phase didn't kill you, this one will. There are so many attacks you might as well put a high score on who can survive the longest. Health: Infinite (Yes. Impossible to beat this stage.) Phase 5: Death. You are dead. This is what you see before respawning. Phase 6: Respawning. A warning to not fight it again.
