I think there were only 4 levels, but it was fun anyway. It's made on the jazz jackrabbit engine.
It's a platformer. You gotta grab loaded batteries to activate mechanisms so you can progress through the game. 3 empty batteries can be traded for a full one.
You're on an energy timer so you'll have to be on the lookout for energy stations.
You gotta collect 3 super batteries and ultimately defeat the Battery Boss.
give it a try, it pretty challenging even now.
