I've played this game right now after update, and what can I say now? Now it seems pretty balanced, well done! But sometimes animatronic's AI is acting too fast, so they are may move from the one cam to another, like skipping their next cam position. It's ok, because their individual sound is helping to recognize which animatronic in which position, but their sound SOMETIMES (more oftenly, than rarely) might NOT be playing, and then it's really hard to know where they are.
But without it, it looks balanced for now! Good job!
