I completed the ending where I destroyed MOTHER by killing all my friends and now I cant go back. Is there a way to go back or restart the game? (Uninstalling didnt work)

I saw the disclaimer saying that it isn't fully voiced, but how much of it is? That was the main selling point of this game for me.

I did. I have instant regrets. I am now scareed for life. Eadit:I meant as an accidentall frist root.

I'm not sure if this game is ever on sale, thinking about it. I should probably stop waiting for a sale and buy full price when convenient.

I have every achievement except this one, and I feel like I should have it by now because its one of the more common achievements. I thought you unlocked it by dating Roobit in the true route and getting Inner Kiane's picture but that didn't do an unlock. Am I a dumb?...
