OUR FIRST GAME BUDDY
Playfellow: a teammate, not a cheat
Playfellow sits beside you like a friend on the couch. It plays your game with you, explains what it's trying, and gets better as it learns your game.
- It watchesIt looks at the game window, nothing else, just like you look at the screen.
- It talksIt thinks out loud and chats, so you always know what it's planning.
- It playsIt presses keys on a list you control, and stops the moment you press F12.

HOW IT PLAYS
Look, think, check, act. Again and again.
Every few seconds your buddy runs the same little loop, and you can watch every step of it.
- LookIt takes a picture of your game window.
- ThinkIt decides what to try next, and says why.
- CheckOnly keys on the game's controls card are allowed.
- ActIt presses the keys, only while the game is in front.
