Yeah. I will probably go in and try to fix it so that customers can't stunlock you, but it is kind of the point. I based my game on my job as an online grocery shopper and having to avoid customers while working against a time limit.
I think the initial blocking works well, and totally makes sense, there just needs to be some way of being able to get away. Maybe their stun could decrease if they block you more than once in some time period?
