I love the art and the music and sound are also really nice.
The concept of the gameplay is also really cool. And I can see how that might be fun.
However. It is way too hard. The player shouldn't die multiple times on the very first screen. And I never got any further than the first screen so I have no idea if the game got any easier or even harder after that.
What adds to the frustration is that the game doesn't seem to be that hard. But it is.
I can't really say much more because I didn't experience a majority of the game.
My suggestion would be that the astronaut doesn't get damaged no matter how they land and have damage only be dealt by hazards in the levels. That way the difficult movement would be preserved which this game builds upon but it wouldn't nearly be as frustrating.
