Wow that was more fun than i expected. The idea is simple you connect cables but the execution is near perfect :D Thinking witch tower needs power and when it needs power is really fun. The sprite work is beatiful the slime enemies look original (for a slime enemy that is incrediable). The tutorial is great at teaching the main mechanic and intruduces new concepts naturaly.
The only negative thing i can say is the player movement and feel. The player is too fast becouse of it i alwasy got electrocuted when trying to connect cables.
Other than this small complaint i want to see this idea developed even further nice work :D
