I love the random encounter tables and the idea that these people are just riding in Kafkaesque subways cars for eternity. I want to hack your hack and my hack into a game about NYC graffiti writers in the 70s. 

• Superb layout design: clean, eye-catching, matches the flavor. 
  
• The Grip mechanic really sells the theme. It matches the surreal elements as much as the more ordinary commuter micro-aggressions.
  
  The rule for Getting A Grip goes a long way towards adding a humanizing element to the game, in a very natural, theme-appropriate way.
  
• My favorite use of randomized encounter/event tables in this Jam, so far.
  
  Given the borderline "magickal urban" setting, the weird mix of possible elements works.
  
• Effective sense of place, even for someone who's completely unfamiliar with the NYC subway system!
  
• I've always found the abstraction of the Inventory system a little odd, but it sticks out even more with the mundane gear (where a bike, house plant, and sunglasses have the same practical/mechanical effect on capacity). But that's a relatively minor quibble for such a well-rounded hack overall.
