subway gates

subway
  start in an empty station
  station exits are blocked by a gate that opens when you press a button
  level exit spawns after you clear 4 stations
  added 2 new stations (7 possible stations)

laser-bots lasers wiggle as it aims at the target
  this is a nerf to iridescence and it looks cool
