Very rich and complex. – Gravitations - Player Made Missions Review

I also enjoy playing 'Trainyard', 'ChuChu Rocket' and 'Smart Sokoban'. But not so much anymore since I discovered 'Gravitations'. What all these games have in common is that you can enjoy playing a huge library of user submitted puzzles. What makes this game the absolute best? Well, this game does have single screen visual solutions just like all of the others. This game uses the timing of events set in motion as part of its solution just like trainyard and chuchu. This game has leaderboards (for each puzzle, as well as an overall leaderboard) and puzzle building for new submissions just like trainyard. What this game has that is unique is a physics engine. The goal of each puzzle is to navigate a spaceship with limited amounts of fuel to its destination through a scenario populated with objects that have gravitational influence on the ships speed. The speed is important in some puzzles so you can save an astronaut from being killed or abducted. In other puzzles you need to time your speed so you can rendezvous with a passing moon to sling though its orbit and gain enough momentum to solve the puzzle using the least amount of fuel. And it is the playing with this physics engine that is the most fun part of the game. You see, many people can try to solve the puzzle the same way, but the person with the most insightful use of the physics will rank higher on the leaderboard. Thus the leaderboard is very competitive, and there is always room at the top when another nuance of the puzzle is discovered by yet another diligent tinkerer.
