I'm guessing it's about that uncommon (but not super rare) condition where a twin's fetus is absorbed by its sibling while still in the womb, and the person is born with a tiny dead fetus in them for the rest of their life, usually without even knowing due to a lack of negative effects.
Not the best, but definitely something new! There should be moral choices though; it'd be cool to be an actual Killbot.
I think this could do really, really well as an action platformer...
There's only one problem I had with this game, and it's more of a glitch than a problem: after you get the Invincibility and get to the room with the weird power core thingy that you're supposed to destroy, you can simply skip it and escape without any plot change. I skipped it the first time without knowing what it was because I didn't know you could shoot upwards... -_-
For anyone wondering, the message at the end reads "Including Ico," so KOLM II is "Kind Of Like Metroid: Including Ico."
Ico is a platform game with a boy and a girl with similar game play mechanics to this game. In Ico, the girl's mother is the queen, who wants to kill her to extend her lifespan; maybe a hint as to the story in Kolm 3?
I considered forcing a moral choice every level, but the only one that came close in the finished version was Botzilla. Maybe in a future game.
