My idea was of connecting or power a few towers at the same time or to have some batery that i can move and power some tower that are close or like you can connect a lot of towers to a power source but for each tower they loose some damage or something like that but I couldn't decide how to do it and for doing it on my free time alone its gonna be hard so I discarded it haha and im glad to see something like that so well implemented. Thank you so much and good luck to you too! ^^
