Still early stage work in progress.
I'm not sure what do you mean by "shield dice" or "hp dice" since there are none of those.
If you mean the red, blue, green, yellow booster dices, those affect main weapon power, give more reactor time and give extra weapons.
The white box is a booster box that gives guaranteed booster pickup.
The ships are getting a "second chance" after one hit later on the line of development.
Surface mechanics and new levels are being made too for more variety on game play.
Stay tuned, and glad you liked the game thus far.
