It seems like fun!
Pros:
The premise is enjoyable, connecting power to the nodes and increasing your defensible area.
Art style was unique
Music was pleasant to listen to
The power node mechanic was very interesting and worked well.
Cons:
The movement controls seemed a little laggy/jerky
No feedback on the tower health that I could tell
enemies might spawn a little quickly or be too powerful, or the defenses are too weak?
