Holy frickin moly, the story just clicked when I finished it, and the boss uses the power ups I collect in the way DAAAAAAAAMN.
This game is amazing, I was wondering why everyone liked it so much, now I understand, and it's 100% true, this game is 10/10 must play.
(one bug I encountered was in my second playthrough, I killed the boss and the boss killed me at the same time, it showed the text of me dying, but then I respawned as the king child, so it's not that bad of a bug)
