It felt cool to essentially attack by multiplying yourself! Instead of trying to minimize losses, you have to defeat the immune system with overwhelming force. It was kind of difficult at first, but I ultimately beat the hard mode level by just constantly swiping my scroll wheel up (which honestly felt really cool) and keeping my mouse in the center of the screen. Even when the screen kept panning away from the bacteria, I could keep multiplying them, and they would eventually catch up with the camera. I could see this being a really unique sort of on-rails, on-the-fly RTS with some balancing to the scaling effect. Maybe there's a resource that dictates how many more bacteria you can create... Maybe to further add to the risk versus reward, you need to consume blood cells to refill it.
