If you're searching for a fun and chipper exploration game to kill a little time with, good for you! Searching is one of the key components of exploration games, so you're already off to a good start. After that, the fun is in what you do with what you find. In Little Rocket, by Alex Miller, you get to explore a small universe AND solve puzzles along the way! Aren't two-for-one bonuses lovely?
Hop in your Little Rocket and fly around your colorful galaxy, clicking the mouse to launch your ship and propel yourself in the direction of your cursor. Your mission is to find the 16 pink stars scattered throughout the many planets around you. Some of them are gathered by collecting smaller orange stars (every fifth orange star collected reveals a pink star), while others are found by solving puzzles on planets. When you land on a planet, you can use your mouse to interact with objects to try to uncover the pink stars. Just be sure to travel safely, as crashing your spaceship, running out of fuel, or flying into deep space will send you back to the last checkpoint planet you visited (all stars and progress intact, thankfully).
The puzzles may not be terribly difficult, and the adventure may be fairly short, but Little Rocket was designed with fun and relaxation in mind. The soothing guitar soundtrack and cheery art are perfect for letting you mellow out and enjoy the game. It's your universe, why not take the time to explore all there is to offer?
