Doors that require a pickup in order to unlock can be opened up with explosions instead.

This also includes any types of chests, even if they don't require a pickup, except Haunted Chests and Mom's Chest.

Also works on Key Blocks and the Strange Door in Depths II.

Doors that require 2 keys only require one bomb to open.

Locked doors can be bombed through even before the room has been completed.
