Thanks for giving it a whirl! And thanks for sharing your goon too!
The combat system is functionally random unfortunately. If they aren't too far away or too close, they have to pick between moving forward, moving backward, doing nothing, or attacking, and sometimes that means they just don't attack. The best current remedy is leveling Reflex so they can make that roll more frequently. Sadly, I had very little time at the end for anything so I couldn't get the better logic in I wanted but that's how jams go.
