How to play Colin Northway's BirdBrain

1. Click and hold on one of the top-row icons.
2. Drag and drop on one of the mid-row icons. This will draw a blue line between them.
3. Click and hold on the same mid-row icon (NOT on the blue line, but the icon itself. Pixel perfect mousing required!)
4. Drag and drop to the bird icon on the bottom row.

To delete a blue line, click on it.

The idea here is that the top row is "inputs", the middle row are operators, and the bottom row is output. By drawing different lines you can change how the bird's brain works.

For example, if you draw a line from "go to food" (arrow pointing to yellow), to the (+) modifier, then to the wings, this will cause the birds to fly towards the nearest food.
