Stargazer is a puzzle game where you can link up stars to create pictures. This is done by selecting stars, and when two are selected a line is drawn between them. There are two main modes, a Challenge Mode where you attempt to recreate images and a Free Mode where you can make your own challenges. The game also supports challenges created by players.
