I'm almost tempted to make a joke thread titled "Chibi-Robo: Zip Lash locks 1/7th of its content behind amiibo paywall" just to see how many people will leap in to complain about something they'll never play.
And yeah, this just further proves that none of the reviewers actually finished the game. Stuff like Mario 3D Land/World and Kid Icarus Uprising had their post-game content always talked about in reviews, whereas I didn't even hear a peep about these bonus levels beyond what was stated on the box.
Edit: Also, 6-5 is 19303.
I would think it would get even more hate than Splatoon since they're original levels unlike Splatoon which were the same levels, but remixed. I'll find out for myself eventually, but I hope it has an extra boss as well.
Also I don't think anyone cares about this, but I think it's really weird that the whole plot of this game is that the aliens are stealing the planet's resources. All you're doing in levels is picking up trash, blowing up UFOs, and picking up candy. I don't really feel like Chibi Robo is helping much at all in the grand scheme of things.
I also might be insane but World 6's music so far sounds a lot like Megurine Luka's "Glasses." It's throwing me off hard.
I'm surprised I haven't run into framerate issues either. I am on a new 3DS though, so that might be the reason.
