Battery was my entry to LD9. The theme was “Build the level you play”. Initially, the open voting hinted at a clear winner of the theme “battery”, for which Hamumu found the best explanation: Battery is a place where bats are hatched. Now, when I woke up the morning of the LD, first thing was I checked the theme, and it mysteriously had shifted. So, I decided to make an RTS where you start with nothing, then have to build up the battery you play.
The title screen.
An in-game shot. Basically, you can order bats to dig (build the level you play), and in the new cave room build different structures for hatching worker and soldier bats and providing food to them. At fixed intervals, a wave of most horrific enemies will attack the battery – so you better have enough soldiers by then.
