Some more details about the game, please?
The video above is not from ingame gameplay! It's just a launch trailer.
It is a game along what we can call a Space Program Simulator. It takes place from a planet called Kermin, The third planet from the sun in a solar system that has some similarities with our own. But everything is scaled down, and the physics challenges are not quite as difficult. There two moons around Kermin, which present somewhat different challenges. There's a planet like Mars, called Duna. A gas gigant called Jool, with some planet size moons... Every planet and moon in the system present a different set of challenges.
There are three game modes:
Sandbox: You get everything from the start, just experiment away and fail. Very confusing and frustrating. Not recommended.
Science: You have only rudimentary rocket parts from the beginning. You then buy more technology, progressively, with science points. The science points have to be earned by succeeding with achievements. There is no budget constraint. This is nice when you start to become really ambitious and want to do very difficult things. Because those complex rockets you will have to develop and build for those mission will require a lot of testing and tweaking. Which costs a lot of money.
Career: Is the most serious game mode. Like science but, you have both reputation and funding to also worry about. The game does sort of guide you and hold your hand, in as way as you must take and fulfill contracts to earn money. But given the inevitable failures, career mode might be difficult to sustain. I don't know, because I haven't played it yet.
Basically, you design and build rockets, planes, spaceplanes and spacecrafts, and then fly them, trying to achieve things with them, visiting different parts of the solar system. Like at first, just getting into the air and survive the landing. Then getting higher. Then getting higher yet. Then getting out into space. Then getting into orbit. Then maybe a rendezvous with one of the moons. Then maybe achieve orbit round one of the moons. Then maybe landing on the moon...
And always, returning and recovering the vessel and science payload safely, earns much more science points than just radioing data back. Manned expeditions also have more opportunities to earn science points, like crew reports, surface samples.
You will also get a better understanding of the physics of spaceflight, playing this game. There is a ton to learn, but learning is fun.
General recommendation on how to play this game: Baby steps. Solve one problem at a time.
The fun of this game is in setting up a goal, then figuring out how to possibly achieve it, then trying and succeeding. One gets a kick out of every milestone.
