Space is a very interesting app. It is by no means easy or even intuitive. Basically unless youre an astronaut or well studied enthusiast, you will find this very difficult and confusing.
Accurate for sure, but super complicated.
There is no tilt control for the aircraft and they require using a thumb stick control scheme, just as the space vehicles do. This is a real pain for controlling the aircraft.
Runways are hard to see, and often fail to even render at all.
The space aspects however are what this is mostly about, and all of that has been painstakingly reproduced as well as could be expected for mobile devices. I mean that to be a compliment.
Tutorials are hilariously brief and unhelpful. They give you a vague idea of whats going on, but will not in any way prepare you for anything. You are going to have to read manuals if you wish to master this or even become a little bit proficient.
Its worth it, but this is not for the casual sim fan.
