This is our perfect ending.
How to Obtain This is it Achievement
Interestingly enough, the hardest achievement to get. In order to get it, you will need to agree to everything your buddy says (except when he asks if anything is wrong, you have to say no), use the buddy button like every other moment, touch no glitches, and not kill the dog.
NOTE: Personally, I have not gotten this achievement yet, but the info here is all bits and pieces from different guides. I will update this once I have it myself with more info as to what exactly goes into this.
NOTE 2.0: As confirmed by the devs, this ending is currently bugged, and they will be trying to fix it over the weekend.
