Since there's no normal thread for this game, and like none anywhere, I'm curious how you get certain game overs I see in the translated Text.
The parasite game over is if you have the Fetal Parasite status (get the Parasite status from the stationary enemies that sometimes grow out of the "seeds" and just don't cure it for at least one level) and go to the flower boss (final boss of World 1).
The hypno interrogation you get by letting one of the VR-goggle enemies attach itself to you, then getting to the Doomsday Machine (World 2 final boss) while under the statuses it forces on you. Stand on the platform that normally starts the boss fight and you'll get trapped.
The Mari game over you get by sitting in all 4 chairs in World 3 (2 in the first level, 2 in the second - you'll know you've found all of them when the chair forces a slave-suit, collar and visor on you) and then approaching the 3-2 boss without destroying the "disc" on the left wall in the boss room.
The parasitic-plant scenes aren't technically game-overs, but you get the plant by going to your room with the Fetal Parasite status active and a Purifier in inventory. The game will prompt you to use the Purifier, which will spawn the plant.
Get grabbed by it once and then just hang around it for the first scene, feed it around 30 Pollution and it'll grow. The first time getting grabbed after it grows will trigger scene number 2.
