I really like the graphics and overall presentation, but I do not think they help highlight the puzzles, which is a shame. I thought I understood the music puzzle once I discovered the moons, but no. Neither forwards nor reverse, the music note code did not work.
And it's a real shame, but after spending 5 minutes just flying and running around the blue planet, hoping to find the puzzle there, i just gave up.
I genuinelly can't tell if it's a skill issue, as I really like puzzle games, but the only one I solved was the red planet one.
