How about adding more clocks to the clock?
When the main Clock is focused, instead of showing survived days, it will turn into the Season Clock:
- Each segment on it represents a single day
- Each season has its own colour
- Survived days can be still seen from the scoreboard
When being within the ruins or having a Thulecite Medallion, the Nightmare Clock will appear:
- Simply shows time before the next phase
- Each phase has its own colour
- Nightmare phase emits a red glow, and has a unique look when the Ancient Gateway is activated
