The game prototype has been updated (0.4.2):

• Neutral creature behavior improvements: boars and moose now get aggro after they get attacked. Hare flees after getting attacked.
• Throwable weapons damage output indicator: throwable weapons now show their damage output when you hover over the card.
• When a predator loses aggro it now triggers a sound indicator.
• Spearfishing is now also possible with the Fishbone Spear.
• Minor bugfixes and small tweaks.

Cheers,

Matt
