In typical advergame fashion, a clever concept turns out to be a half-baked product tour that never deviates too far from a brand narrative. Apparently you don't even get to fuck anime Colonel Sanders!
In order to romance the colonel, you have to choose the correct dialogue choices when the game presents them to you. There are wrong choices, and you can lose if you pick them. I got a game over after being too forward with Colonel Sanders after trying on one of his white jackets. I'd selected the option for making my "big move" in the outfit, which I guess was supposed to have a sexual undertone that I didn't pick up on until afterward. The choices are mostly straightforward. The only thing that Colonel Sanders really cares about is chicken, and most chicken-related dialogue choices will take you pretty far.
