Use faces

[quozl]

• discard circle, rectangle, and triangle shapes,
• show the player with a face instead of a simple circle,
• show local bonus players with eyes facing toward extra controls on XO laptops.

Not sure about this change. The difference between players is too subtle (also eyes direction can be interpreted as movement direction). And maybe is better use a image file with the face instead of draw it with cairo.
Just my humble opinion, I gave you commit access to the repository.

Thanks. Yes, I struggled with that. Different colours are used when collaborating over network.

The use case is local keyboard without collaboration. On the one hand, children are generally excellent at identifying direction of gaze, and any practice is just fun. This arises from infant neural networks, and becomes part of the mirror neural response. For those with undeveloped mirror neural response the game will be that little bit more challenging.

I'll rework it to use monochrome for the local bonus players;

• black background with white ring,
• grey background with black ring.

An interesting hidden use case is to activate the local bonus players while in a network collaboration game; they don't appear on the other displays, so can be used as markers.

Thanks for the feedback. Change made, force pushed, please review. If okay, I'll push without merge.

I've chosen not to use black background, but instead two shades of grey that are difficult to differentiate when the players are a long way from each other. My guess is that differentiation, without looking at the eyes, is really only needed when the players are in close proximity in the maze. Screenshot of close proximity in simplest maze:
