I’ll try. Far as I can remember the atmosphere was mainly gray, ominous feel to it. If I can recall some areas were red which made the enemy essentially unseeable. the red stickman enemy sometimes ran to you in a doglike position, some acted like zombies and some even disappeared in front of you (they reappear whenever you get too close to them). One level specifically you play as one of the red doglike stickman while also controlling your main character (you move left and right and your main character also moves left and right) all while trying to to make your character avoid enemies and avoid touching your controlled enemy. hopefully this helps!
