The game is great; the graphics and animations are really well done, and you can play it for a long time without getting bored. If there’s one thing that could be improved, it might be the way the ship becomes unstable when it’s running low on energy. It took me a while to figure out how it worked, and I think the instability should be smoother and more predictable, to give the player a chance to recover. But I really enjoyed playing your game!
