 make a seed/hash system that controls only the tech/guns/fields shown
+  URL sharing could include a seed
   seed will control:
-    seeded random at start done - random level boss, mob types list, level order, horizontal flip
+    seeded random at start - random level boss, mob types list, level order, horizontal flip
     seeded random during run - tech, gun, field choices
     not seeded random - mob spawns, mob size, minor level differences, custom level boss choices, ammo rewards, tech effect randomness
       better to only seed things at the start of the run so it doesn't mess with power up choices
-  put a seed display in top right corner of splash menu, or settings?

-    normal seed = full UTC time
