Reverse minesweeper where the target moves; a simple idea, well executed.
The music, visual, and dialogue effects are all fitting and well designed/chosen, the shooting star being particularly awesome. You might consider adding a visual arc pointing in the general direction where the astronaut went next (from that planet, not where they are now), to help the player continue their search on harder levels. Otherwise, it feels like a lot of guesswork.
Nevertheless, a well chosen design for this Jam. Good work, and good luck! :D
