Thank you so much for trying my game!
There should be a sound indicator for when the enemy is close, but as you said it might be a little low volume. You are not the only one who has gotten a little stuck after talking to the dog a second time, so not as much a you problem. I should probably adjust that part a little so it is easier to get away. (A little hint for getting past it though: don't climb down)
Thank you for the feedback!
