1. Momentum is a good thing. The higher your momentum the easier it to overcome a Hazard. You are correct on the Momentum ruling being weird, I think I have it backwards on the rule sheet right now. The rules for hazards should be:
- Rolling equal or under is a success and you reduce your Momentum by 1.
- Rolling greater than is a fail and you lose 1 Stamina.
2. This will be clarified as well in a new upload as I realize there isn't a rule for keeping Hazard cards off to the side. I'll probably just change it to keep thing simple as I'm already limited on free space.
I like your idea about using Aces for Unique encounters and might include that in the update. Going to a 6 in 54 (from 2 in 54) chance of a Unique event happening would make things more interesting for sure!
