[edits: turns out it works a LOT better when I use my actual id and not -1!]

A dumb little bot that runs around the board, doing his best to attract attention and draw chasers, and then run to the middle where (hopefully) he'll find somebody to help him, or he'll just stall the chaser and stop him from hunting.

Doesn't seem to make a huge impact on overall score due to how powerful the Blue tagteam are, but at the very least I didn't make things worse!

Shout in the next 8 hours if you want me to add anything useful to my message.
