Thank you for your amazing review. We are very happy that you liked our game. We continue to work on it and hope that soon you and the rest will be able to see an improved full version of the game.
In answer to your questions, the little red circles are something like footsteps in the dark, they are added for the atmosphere. The enemy behavior is actually a bit random, we didn't specifically create the enemy behavior to become more complex, but it sounds like a very good idea to me.
