PolyLines 3D - spatial puzzle

I love the music! This game is so relaxing. Is there some way to get rid of the ads?

I'm really happy I found this app. I was especially looking for something to exercise spatial awareness, and this is the first one that I have liked. Even doing the same ones repeatedly is enjoyable. There are about 30 free levels and each can be done on easy or hard option. There are no ads which is wonderful, just an option to pay to unlock a lot more levels if you'd like to. I have now paid to unlock the other levels as I can see it's really worth it. You have a small introductory level, and then you're on your own. The music can be turned down, but it's ok music but does get repetitive. The game itself I just love it. The images are beautiful and very rewarding when you complete each one. Below I have written instructions for how to play hard option, which I only figured out by trial and error, as there are no instructions for this, hence one star off. I hope I have helped people to not get frustrated with figuring out how to play hard level. What you see is half the lines in the background and half the lines are bright and moveable. When you have moved them to how you think is right, you click the 2 overlaid boxes at the bottom of the screen and this swaps the moveable lines into the background, so that you can work on the other half.

Fun, a bit challenging at times, and the prettiest one of this genre. One star deleted because it seems the game is abandoned by the developers. The auto generated shapes are beautiful, but having actual shapes is fun, too. Also, they should add more difficult shapes.

My favorite puzzle game of this genre. It's fairly challenging, and the graphics are pretty. The only downside is I wish there were more levels.

Level 71 is broken. A bit repetititititive, but a nice calming experience IF YOU CAN HANDLE CRAZY ADS WITH ZOMBIES
