I call Nier:Automata "the best game I will never play again" and it's because of 9S' combat.
What were they thinking? No one cares about 9S anyway! But he's your playable for well more than what should only have been his one-third the game, and his combat is AWFUL! If I wanted to play Asteroids I'd play Asteroids. You have two other playable characters, both of which chop up robots with giant swords! THAT'S what people are here for, know your audience!
There is a video demo of the bug later on the thread.
Some android devices have a combination .- key on the numeric input UI. This is a contentious enough design choice to have stackoverflow threads on it. That combo key style is what's used by the device and version shown on the demo. It appears that the device is reading that combo key as - and discarding (or taking absolute value), and not as a leading decimal.
This may come as a surprise to some whataboutists, but it turns out that multiple things can all be senseless tragedies at the same time.
NSA be like: "dude shut up you're going to blow it for all of us!"
