Not always obvious when the Trials timer has finished and the player needs to select their answer

Some players don't realise that they need to select an answer. For example, they may have turned 180 degrees, and the prompt about selecting an answer is behind them.

Potential options:
- Change the buckyball visuals when in selecting mode
- A small noise plays when the selecting mode starts
- The prompt is place on the wall in front of the player, so will flip if the player has turned around.
