First off, I just want to say what a great time I am having with this game. I love how I am allowed to progress at any pace I want without getting the feeling of doing something wrong or missing anything. If I want to carefully explore a building or just skip around a whole region, it always feels “correct.” I have a lot more praise to give, but I’ll skip to my question to stop from getting too far off topic.
When exploring the underground, I have discovered orange boss rooms and yellow gem rooms. When I successfully defeat a boss and then leave the room, the orange color disappears and the room name changes to “former boss room.” When I mine the deposit in the yellow gem rooms, however, the yellow does not go away. Have I just missed gems in every yellow room I’ve been in? Could it be that they re-spawn later?
I ask because I can’t seem to tell the difference between two gem rooms on the map, both of which I have entered, but only mined the gem in one.
