This is a cool idea for a game and I really want to play more of it. The music and atmosphere is nice but I wish the green square wouldn't dilate throughout and jiggle if you go against the wall. If it's possible to make the walkers go faster after they've avoided all dangers that'd be great (though that would defeat the purpose of calling it "walker" and not "brisk pacers"). Either that or being able to move the square faster would help. The story behind it is surreal but in a good way, props on you for that.
