I have this idea called Bronze Keys(or should it be called Energy Keys, or Spark Keys?). I got the idea from the Sparks of Life replacing energy. Since reviving used to depend on mist, and now it has changed into an item, it's a good idea to do the same for energy gates.
Bronze keys would be found in treasure boxes; or bought in the supply depot for 25 energy units per 10, which is worth 2.5 energy units each. If a player finds a energy gate, and has a key, the player can use one to unlock the gate. If the player doesn't have any keys, that player would pay 5 energy units instead of the current 3, making it double the cost of the bronze keys in the supply depot.
So, what do you think about this idea? Do you have a better name for these keys?

I like the idea, would help for mass danger room runs/graveyard boxes/tortodrone mysterious rooms. This would be good/bad depending on how it influences people to open the energy gates.
