Ah this reminds me of Moon Lander, from 1979. Hard as hell, but rewarding once you get it. I wish when you landed, you would get locked to the planet so you could choose when to get away, because I kept dying trying to get off the moon. Nice work!

The game is too difficult, and not in a good way.  The rocket does not aim towards your mouse, but rotates left and right based on the mouse.  The gravitational pull of some of the planets is too strong, resulting in you dying after landing on one.  The fuel system doesn't work well with the gravity of the planets and just adds needless stress.   Sometimes you can getaway with sliding against a planet, sometimes you just die barely touching it.  It is possible, I beat it after many tries and a good planet order.  The randomization of the number of planets is cool.  The concept is fun.  The game could be very fun with better controls (rocket aims or aims away from cursor),  consistent hitboxes (might not be the right word),  no fuel system or a way to get fuel, and less pull mainly from the smaller planets or a new mechanic that solves this problem.  The game is already fun but needlessly frustrating.   The artwork is nice and so is the music.  I would lower the volume of the thrusters or make it sound nicer as you are hearing it constantly.  With just a few changes this would make for a very fun and casual game.
