Rakete is a game about controlling 5 rockets on a blocky spaceship to maneuver through levels without touching the borders. Graphically simple. It can be played single player or with up to 5 players each controlling one rocket. Even with only one person (thus no need to worry about coordinating efforts) the game is still very difficult once you get past the first twenty or so levels, and is very likely to require multiple re-tries for each level. It took me about 3 hours to reach the final level, so it's only recommended if you like a slow-paced challenge.
