I positively love the games from Pyrosphere. Just the other day, Federico Prat Villar noticed that I didn't mention
The Weaver when I recently talked about Ribbon Puzzles. I had never heard of it.
Last night, I downloaded it & solved all 150 levels in about one hour. It's not hard. But the graphics & interplay are splendid.
The objective is to get all the ribbons to pass through a matching colored square in the bottom right or lower left side. Tap on the intersection of 2 ribbons and they will swap directions. That's where the graphics are magically wonderful.
Where things get more interesting: instead of having an orange square as the goal, that square might be a blue rectangle with a yellow rectangle. That means that either colored ribbon can pass through that space. That's where it gets a bit tricky.
My one qualm is my score for each level. On some levels, where I struggled and took a lot of time, I got 3 stars. On other levels which I solved effortlessly, I got only 1 star. As I've said in the past, I'm not a purist that needs to solve each level with the minimum # of moves.
