Very polished UI/UX. I'd say this is far closer in similarity to TimeGuessr than GeoGuessr. The only difference is that in TimeGuessr you are guessing a year and a location based on a single real image whereas Time Portal is making heavy use of GenAI for image/videos. Anything I'm missing?

OP: You might also want to change the title in your HTML header for the game - it just says Eggnog which is kinda funny but not sure if that was intentional.
