Game
The game is designed to teach the user to recognize all the 88 modern constellations, brightest stars and 110 Messier Objects by taking them through a number of levels. Levels are divided into categories (constellations, stars & DSOs), regions (north, equator, south) and difficulties (easy, medium, hard). Each level teaches only a small number of objects and then trains the knowledge in a quiz game to aid memorization. Later levels also review and retest the knowledge of previously learnt objects.

Levels
In each level, you're first given an opportunity to see and memorize the objects (constellations, stars, or DSOs) of that level. Use the arrows to go through all of them, and click 'Start' once you're ready. The description of each object is displayed on the panel at the bottom of the screen. The panel can be expanded by dragging it up to show more details about the object. After clicking “Start”, an object will be shown and you’ll be presented with 4 options. The level ends when you answer a certain number of questions (shown in the top-left corner) correctly. At the end of the level you'll have the opportunity to review the mistakes you’ve made before progressing further. Please note, in challenge levels, no hints are available and you are given only a limited number of lives to pass them.

Difficulties
Each level is available in 3 difficulties: easy, medium, and hard.
Easy levels show the lines of the constellations, making the experience less similar to the real night sky, but it's the first step of learning.
Medium levels hide the lines of the constellations, but show their precise borders and the lines of the surrounding constellations to help the recognition.
Hard levels are closest to the real night sky: they only show the approximate location of the objects, instead of the exact shape (the borders), and randomly choose the orientation each time, so that you learn to recognize the objects from another angle.
We recommend going through each difficulty, from easy to hard.

Explore screen
The explore screen (third button on the main screen) allows you to explore the sky on your own. Tapping on the objects (e.g. names of the stars or constellations) shows more information about them (e.g. abbreviation, brightest star, area of the sky, bright stars, distance etc.). You can also use the same double-tap gesture to quickly hide/reveal all the decorations. The search icon (top-right corner) allows you to quickly find a particular object you're interested in.

Have fun learning constellations and stars in the sky!

Recent changes:
- Besides constellations and stars, now the app teaches and trains 110 Deep Sky Objects (Messier Objects).
