Moon direction wrong

This is a great concept, but the moon direction seems wrong. It shows the northern hemisphere at the top, so the moon should be orbiting counterclockwise. Also, it would be nice to show the earth rotation based on the current time of day.

Response from developer

Thank you for this constructive feedback. You were right on both counts, and we should have caught it ourselves. The orbits were being drawn clockwise as seen from above the north pole, when the real solar system runs counterclockwise. Everything was in the correct position relative to the Sun, so it slipped past our checks, but the direction of travel was mirrored. That is fixed in the upcoming 1.4 version. Regarding the second suggestion, Earth now rotates to the real time of day on Today in Time travel mode: the daylight side is where daylight actually is. We will have more dedicated features for Earth soon, please stay tuned. If you spot anything else, or have other ideas, please feel free to contact us anytime. Feedback this precise makes the app better!

Such a beautiful educational game!

this app really emphasizes and bridges the educational and pure wonder of learning about space :)
