I don't understand how the skill tree is supposed to work
Is it just me or do just a few runs allow you to unlock pretty much everything in the skill treeup until the next boss node? Only exception are the Halicron which seem to be limited in quantity so as I progress more and more upgrades that require those are becoming inaccessible since the upgrades seem to get more and more expensive. Therefore I am focusing on unlocking only those that block access to further lucenite upgrades.
Is there more to it?
It seems incredibly simple and devoid of strategy nor does it seem to provide any build variety. That can't be it though, can it?
