It adds two items (currently, updates are coming)
It adds sushi
It adds a burger bun
Both items increase your movement speed
sushi is made with 10 raw fish, gives 4 sushi
burger bun is made with 4 wood and 10 sushi, gives 1 burger bun
My thought was to add something to make movement in the early game easier. (Speciall if you're playing Pyanodon or Seablock, you quickly have a HUGE factory and really nothing to be faster)
