I think the timing is perfect to have a tutorial for all endings! ^^
As for the story, I really like how it's centered around a very common situation that is so dreaded by many XD You had such a good eye for the potential in there, and what's best: you executed it in a deliciously humorous way!
I also liked how the choices were a fundamental part of the narrative, and how the reader really must pay attention if they want to reach the perfect ending quickly.
The one thing that stuck with me a bit was that, personally, Kelsie's reactions to some minor situations made me detach from her character. For instance, when MC bears the "wrong" gift to her parents (despite arriving in time) she just gives it a disapproving look and doesn't say a thing.
As the player, I understand the hint that it wasn't a good decision, but as K's girlfriend, it makes it seem like we're not a team but rather that I'm in it by myself, in a way.
I believe that's due to the fact that, in a short story, every little action seems bigger to the reader, as it's only through them that we have insight into who the characters are.
It didn't affect the experience much though, and I had tons of fun: I was the jerk that got blocked, I was the neutral partner that didn't last for long, I was the crazy guy who broke her father's hand (🤣🤣) and I was the perfect match that lasted, too ❤
Great work!!
