 I haven't had a chance to work through the retro lab yet (I did watch the video), but wanted to get this proposal in first. I think some of the easy movements will become more obvious to me after the retro lab. I think one challenge may be making the hungry man larger and the subsequent navigation around the screen. If this functionality does not become too challenging, I may try to add different types of snacks for the hungry man or different types of penalties. 
 
+# Feedback from Chris Proctor
+This sounds like a fun challenge--and I think it's a good conceptual distance 
+from the snake game that you'll be able to study that game's code. One major challenge
+I anticipate is coordinating all the pixels of the man's body. The snake game has
+one approach--the head moves forward, and then each body segment moves into the position 
+previously occupied by the segment (or head) in front of it. This involves propagating
+a message along a sequence of agents, similar to what I had to do with the blocks in 
+my beast game (see week 13 video). 
 
+Another approach, which might work better for this game, would be to have a body manager 
+agent, which has a position but isn't displayed directly (`display = False`). Then body 
+part agents (each agent that actually shows up on the screen) each have a fixed (x, y)
+offset from the body manager's position, which acts as an origin point for a local reference
+frame. The body manager can keep all its body parts in a list, and an `update_positions` 
+method which goes through each body part and sets its position to the manager's position 
+plus the body part's offset. That way, you can move the whole body by moving the manager 
+and then calling `update_positions`.
 
+Good luck, and be in touch when you get stuck!
