So this is something i made in one of my many stream-of-thought things that i occasionally have when talking to my friends. This is official House Runner canon here. It also explains a couple of the frames within the game that are kinda confusing and seemingly out of place.
featuring skype conversation things at the beginning of each line

[12:57:53] lin: see now mr. pickens has the control tower as his home
[12:58:09] lin: and for some reason he decided to put multiple locks on his door
[12:58:21] lin: and it just so happened that he put one too many on
[12:58:43] lin: and he actually fell out from his home where upon he got dragged to where you start
[12:58:49] lin: hence why all the keys are on the floor
[12:58:57] lin: and the keys have become sentient over time
[12:59:08] lin: and if they detect human life they will move away
[12:59:10] lin: however theyre fine with sinks
[12:59:26] lin: so mr. pickens dressed up as a sink in order to get all his keys back so he could get to his house again
[12:59:35] lin: AND THATS WHY YOURE A SINK COLLECTING KEYS IN THE LAST LEVEL

[13:01:01] lin: if it becomes night time then none of the keys work on his door
[13:01:17] lin: so mr. pickens would be locked out of his own house if he didnt get there before night
