I played the web version. It's seems to freeze a lot at the start of a game, and once "crash" completely. But again, didn't tried the .exe.
It's hard to understand how to "move" the ship. It took me 4 tries to deliver 1 package. Because I didn't understand that you can't accelerate when close to a planet.
The ship handling is pretty hard to get a good grasp of. Took me a while to get how the hook physics worked, but it's kinda fun
I also don't see most of the time the arrow that points to your destination.
Audio is really fitting, so calm.
