I like how the position of the ship on screen and particle effects show you current speed and direction :) I tried to solve it in my game by just showing a semitransparent overlay with dust-like particles that you move through without parallax (while background is parallaxed). The variety of movement and energy hungriness difference between ship and rover was also nice, I didn't expect such a complex game at first :) I also liked the visuals. It's a pity there are no other sounds than rocket engine and drilling (unless I missed something). And the escape button mapping is pretty gatekeeping on web builds, with fullscreen it exits fullscreen first, so needs to be entered sometimes 2-3 times to actually pause and see the controls 😅 Generally engaging, I had trouble understanding how the green rock gets transformed into energy and how to pass it from rover to ship (still not sure if that happened). At the end I just blindly flew the ship for fun for some time around till the energy reached 0 to see if there is an end game screen. It was fun, surprising for me that you have so little votes! :O
