About batteries, i mean just standard place-able batteries.
This game reminds me PlantsVsZombies, and i expected mines analog. (Yes i know, sunflower - battery more intuitive, just talk about my impression)
And yes, overload, add new mmm sides to familiar game mechanic.
I take it back, fridges useful... My new best. (Trick just in placing fridges in front of big enemy wave to delay it and be quickly destroyed before overload with new row wave)
