I think that you should earn gold and fame when you complete a quest. The more quests you've completed, the more you get, also the difficulty of the quest.
Basic strategy to any and every map: Get a medium to large sized Reactor farm, (depending on the closeness and intensity of creeper infestation), make a farm for offensive weapons to deploy where needed , when needed. Place Beams closer together than you think. This is so that more than one spore doesn't come and overpower you.
End of guide.
OMG !!! You found the secret boss coin reward of doom !!!
