Yes I read the entire thing, don't use screwdriver on kitchen door before carrot.
My problem here pertains to a strat I thought about that saves about 1 seconds (ik big time save) that may or may not be a loophole. After you give the carrot to pony, the kitchen door doesn't necessarily open UNTIL Katie gets to the vent. With that in mind, the duo can communicate. Player 1 will give the carrot, then Player 2 will use the screwdriver the MOMENT the carrot is given, and not wait for the door to open up. After all, the rules only said something about opening the door BEFORE carrot, not AFTER 1 seconds of carrot being given.
If this is not supposed to happen, it'll help if you make this clear in the rules, it's kinda easy to find a loophole
Just use screwdriver after the door that you can see is in front of the screwdriver door is gone for it to not be considered a glitch
