The swarm towers were the last that I got working so they had less testing and balancing. I also vastly underestimated all the different moving parts that goes into difficulty and balance with a tower defense game. So if things are even the least bit balanced, I'm happy. I wonder why the FPS gets so low. Is it just natural from having a ton of things on screen or did I goof up something like stuff isn't getting deleted properly? Might have to look into that. I'm still learning Bevy, but it's been fun so far.
