I’m playing with challenges so no special plants Spawn in any hidden gardens. If the door is hidden you know it is a hidden garden but I completely forgot if it was originally hidden. So is there a way to differentiate the two? I may have to look into the source code to even figure it out, if no one has an answer.
Oh okay! I didn’t realize you were looking for hidden rooms for exploration score.
Your best bet is probably to check out the wiki section on floor generation for the details on hidden rooms.
