Should I call it Power? Should I call it Energy? Dunno.. doesn't matter. Power sounds great. Energy sounds great...
So now we spend Power for everything functional in this game. That means Life, Upgrades, Skill Changes, and especially Teleporting to new levels, they all cost Power.
And now the UI has updated to reflects these changes. Gone is the Circle of Life.. it has only stayed in the game symbolically, as one of the signs. The sign graphics tho.. can very well change later. : D OK, so instead of the Circle of Life, now we have a Life bar, a Power bar.. and an Upgrades bar with the unlocked Signs icons below. Now we can understand better what our Character Build is made of.
Also for clarity, all Power Items in game will glow when you get near, showing that you can Power them. You only spend Power if you actually activate them, by getting very close/walking thru their center.
Oh, and don't mind the stupid AI. They're about to be reworked..
