I agree with this - ECS lets you write totally decoupled, composable bits of game logic very easily, which is super powerful. But in my experience if you're not careful you end up with a hundred perfectly decoupled little things and it's really difficult to remember how they actually all come together to make the whole game you've built.
Easily grokable filenames and file structure are very important, and bevy specifically has a pretty nice plugin system which lets you really clearly 100% isolate groups of state/logic into more sensible sections instead of ultimately having some root level game loop that's directly setting up your 100 tiny little poorly named things.
