This game looks great--the player character, the little cosmonauts to rescue, the obstacles and background. Everything is distinct and stylish, making the most of the low resolution and the limited palette.
Also, I wasn't getting sound when I played--if it was implemented, for some reason it wasn't working for me.
The big issue for me was the extreme difficulty. It crossed my mind that it might be almost as hard as flying a real spaceship. :D Even in Level 2, the solar winds were just tossing me against the scenery over and over and over... I couldn't really wrest control.
