Alright. I still want part of the game to be a mystery, and about not knowing what to do, and figuring it out... But I want it to be figure-out-able. That's why I tactically used the color red, to draw your attention.
I noticed my coworker had difficulty noticing the lock, and being pulled out the car window was much too fast.
Is that also your experience? Maybe just that one part needs to be honed.... At first at least.
