Overlays
Overlays are used to display information in the HUD scene. Although overlays are similar to entities and their components, we wanted to completely separate them from the entity game logic.
Timer Overlay

This overlays shows the timer with a little hourglass icon which changes based on the remaining time. When the time is running out, the hourglass is empty and starts to blink.
Health Overlay

The health overlay shows the player's health. Next to the hearts is a gravity-shift vote indicator which shows whether the player has voted for a gravity shift or not.
