Has issues playing with others
The minutes-long, excruciatingly-boring intro movie is not my biggest concern about Shiftlings so far. That honor goes to the fact that my second player and I completely failed to get local co-op to work.
Our experience was just as this poster describes, where the game's functions seemed to become split between two controllers. (It reminded me of my controller issues with Sonic & All-Stars Racing Transformed, which is not good company to be in.)
Local co-op was the whole reason I bought Shiftlings, so I was prepared to write it off completely until I found this post claiming that it "works," but is terribly messaged by the UI.
After calibrating once, both controllers work in-game. Note that only the first controller works in the main menu, though, which arguably can be confusing.
There should be a text in the top-right corner of the screen saying something like "join the game by pressing Return or Start on second controller". It disappears fairly quick, though, so it I guess it's easy to miss.
I'm willing to give it another try, but this bullshit has already soured my opinion of Shiftlings significantly.
