I love the idea of reversing the myth and playing as the monster, but I agree with the previous comments that it shouldn't kill the player if they run into walls (which seemed to happen to me as well). Because its incredibly easy to overshoot the movement, in fact its almost optimal to mash the keys to move as quickly as possible were it not for it killing the player.
I did actually manage to win once I had the pattern down of who escapes the fastest, but its kinda a steep learning curve without an explanation of whats going on.
