The implementation of the software, the design of the puzzles, and the game play are all mind BOGGLING! Everything is top notch.It takes a little while to get good at slelecting and sliding some of the smaller pieces, but once you get the hang of that, its very natural. Very smooth and seemingly bug free.The written hints are at exactly the right level of hint-osity. They keep you from dithering aimlessly and give you a needed leg up so that you can focus on the intersting part of the game, solving it. I used the written hints on almost all the puzzles, otherwise I think I would have given up. Consider yourself a genius if you can do this without the written hints. Actually, I think you would have to be an idiot savant, but maybe I am the idiot idiot.Suggested implementation improvement: X-Ray mode. If you know Sketchup's X-Ray Mode, I think that could really help the game play here. Sometimes you have to spin the playing space around in order to see where the collisionis taking place. That gets in the way of the interesting part of the game.I solved all the puzzles in about a 48 hour period and I was pretty glad there weren't more. I guess I have OCD and this game triggered an obsessive/compulsive behavior trait. So I was glad the puzzles aren't computer-generated and infinte. How do they generate these puzzle. Talk about a genius! WHomever designed the puzzles has my utmost respect.

I’ve had this game on my devices for the last 5 years. When I first started playing, I wondered why I felt so relaxed, had a clear and peaceful mindset and didn’t want to stop playing. It took me a minute to realize it was because of how beautiful the music was. After that, I’d go back and just open the game up and leave it on one of the levels and set my screen to never turn off, just so I can listen to the music. I got back on a couple days ago and the music is gone!😭😭😭😭. Please return it!

The puzzles are challenging and work. Haven't found any bugs. As I was playing I found that I could not solve many of the puzzles. When you click the skip button the app will show you how to solve it. I like that it does that, but it won't let you move the angle and it solves it quickly, which makes it hard to understand. This means that I have to watch multiple time, which is fine, except for the fact that you have to watch a 30 second ad for each time you view it. This only makes my current frustration worse and for this reason I am going to find another puzzle app. If you don't mind watching a lot of annoying ads while you are both frustrated and trying to find out a solution than this app is for you. Other wise I'd recommend finding something else.

And sometimes really hard, but I have finally figured them out. At first, they were so challenging I lost patience. But I have finally got the secret, or at least a way of working thru each puzzle. It may take me a while, but I don’t care about the score. It’s just an enjoyable and relaxing game. Nice graphics and movement. Thank you guys. When you get around to it, I could use some more. Though I’m not completely done with all the puzzles. I just wanted to put in my pleasure over this game. Nicely done.Candy
