My experience at Bloomberg was exactly this: devs telling me that putting a button in some place is impossible, then insisting on implementing an animation system for feet on staircases (we made a spreadsheet product)

Like building a framework so that players can fire off 5 abilities at the same time, and the game designers are still iterating what the gameplay will even look like! How much time are you wasting?
Or making an entire animation system for feet on staircases: Will the game even have many staircases?
