Thanks Boris. I'll take that as a compliment. Though it also may indicate that I have NO LIFE.
What's different? The asteroids can travel, but the suns are fixed in place. Also, on some levels, the spaceship must pick up the green gas tank before getting to the galaxy. Some levels have wormholes, naturally.
One of the bad things about being a puzzle app blogger is that one often plays the earliest version 1. I was stuck on level 18 for a while. Sometimes the undo and refresh buttons didn't work. But the exit button did. However, the program would not let me do 18 until I redid 17 again. I ended up doing level 17 about 5 times before I figured out 18.
The same thing happened to me on level 51. I contacted Boris to check it. He confirmed it to me: it was impossible. Meanwhile I solved level 50 about 10 times.
However, Loyal Blog Follower, Boris has fixed all of that! The new level 51 is solvable. Alas, I asked Boris for a hint. Then I rapidly completed the rest (58 levels altogether). I think I noticed that level 57 is the same as 51.
The graphics are crisp & clear.
If you're a fan of Lunar Lockout, I think you'll enjoy these new challenges. I did.
