I won't lie, I honestly think the end part is just poorly put designed, after having the player get so far I should've more clearly conveyed what they were supposed to do.
I gave the player about 2 seconds of time to react, and in a game where the whole time you've been taught to run, almost every player of course will naturally try and run and get confused when they can't move, then die to no fault of their own. It's a lesson I will take in the future to not be so VAGUE, or at the very least more forgiving with checkpoints or something.
Thank you very much for the feedback!
