Very clevel puzzle game!
Nice art style and playing nicely.
Puzzles with nice progression and interesting mechanics to play with!
Also, I like what you can messing around with gravity, it's so fun!
As for feedback: my main concern is too many keyboard keys for simple elements which could be simplified I think. Like to allow to play it only using keyboard but throwing only forward or more use mouse cursor to allow mine when click on the planet you're in, pickup on click ores you've mined and throw when you click with ore equipped and click on robot to drop ore you're equipped. So in that sense FEQ keys will not be used for mouse-heavy playthrough. As you can see I had a little bit hard time to remember which key do which action at first.
