About your point 6. I’ve been wondering what you’ve meant with space bridges, but I guess you refer to the 3 mission portals. (Easy, Medium and Hard Missions).
It depends on how hard you are in need for crystals to make use of them. Of course how longer the mission lasts the greater the reward will be, but you can’t use the bots during that period for anything else. So make a good choice for the bots you are gonna use (ones you don’t expect to use on short term). It might also be worth considering to shorten the mission by maximal 50% by spending pigs.
Also if you need a bot on the mission desperately, you can always end the mission by spending gems to finish the mission. But I don’t recommend this (waste of gems).
I preferably use the portals if I’m gonna be offline for a while and don’t need the bots.
You can view the topic Mission Portals for more info.
Btw, I still don’t know what you mean with the extra key pics so I can’t help you with that question. If you’re referring to the question marks, these are (I think) either coins, crystals or a limited amount of gems (if you’re lucky).
