It's Good but a few things:
Those Whiteish slimes annihilate barriers far too fast. I've had to scrap a run because of this.
I like the 'balance between power for you and power for your buildings' but it could use with some sort of 'connecting power' UI instead of just by proximity, as buildings will sap power from a source even if they already have enough from the one on the other side. It'd also be nice if you could use power sources on platforms to power things below them. Otherwise platforms are of minimal use.
Basic elevator could be smaller.
The arc generator thing's tooltip is unclear. Is it ranged or is it like, close proximity?
All that being said, the animation has improved and the extra selection of characters is nice as well.
