Nice concise level but after about 20 times I can't get the balls to all fall correctly which I thought was the intended solution. I can win with only one ball though.
@gmacpro Thanks. Spoiler Yes, you can finish by riding the first ball and not using the second. Either way you have to make your decision before Ball 1 rolls out of reach, or B gets stranded.
Nice 'n simple small ball level. Fun. Not a fan of incomplete rails though. (worked on my first attempt)
Nice and easy, had no problems with it. Nicely compact. BTW: I went to check the comments on your level Sci-fi city, and it's been deleted?
Found a way to get the first two balls to drop as needed quite consistently but really struggled with the third ball, which was likely a result of my own lack of patience. Still a fun level all around.
