Rocket Engineer

Rocket Engineer is a game about designing your rocket part by part, instead of having prebuilt engines like most rocket games, Rocket Engineer let you design your parts with as much details as possible. 

As of 0.0.3b, the currently included features are tank designer, engine designer and a small solar system including the Sun, Earth and Moon. This version is still a prototype.

0.0.4 is the version we're currently working on is a much more polished version that will include the next big part of the game: testing. As you are designing the engines by yourself, you will also need to test them so you can know what is the thrust and its ISP.  Same for the tank, you will know its max quantity.
