Excellent game with one complaint

I am addicted to puzzles and finding good ones on the App Store can be a pain but this suited my needs perfectly! I'm an artist and love colors, this helps me understand them even more I think. The component of solving a puzzle makes it all the more great!

I have one issue though, dark values are next to impossible to see. It makes it much more difficult and not in a "that's part of the challenge" way. I wish there was an option to change the background color, maybe to white or a soft pattern or something to help stand out a little more.

The animations of the level select are kind of annoying too, and it's hard to see. The game seems a little... Small? There's plenty of space too so I don't see why it needs to be like that. Maybe I need to rotate it to landscape but that's more or less just a bother to me.

Organizing paint chips- FYI, works on iPad mini!

This feels like arranging paint chips from light to dark or vice versa. Then opposites on the color wheel come into play. Still a beginner in both this version and blendoku2 - can't believe the world records are so high that I beat them ? Something is just wrong with that!

Agree that I would like to see it larger. I have poor eyesight but can still discern gradations so I like both versions. Also agree that navy blues and other dark colors can be difficult to discern against dark background, skip those...

Kudos to developers for thinking this up - and allowing you to just skip the ones you don't get, occasionally very frustrating but mostly fun so far. If you like "flow free" you will probably like this and vice versa. Enjoy! And improve the goofy world record numbers as they are meaningless so far.

Fail on iPhone 6S Plus & iPad Air

Great idea but unusable. I absolutely loved plying.

However, on both of my devices the menu will not show. That is, when I am playing and blending blocks, there are no buttons at all visible on the screen except the "?" In the upper right.

According to the screen that comes up when I hit the "?", there are supposed to be other buttons such as the Back button, the Settings button, and so on. In particular, I have not been able to find out how to get a Solve.

After 50 years as a computer programmer, I am generally pretty adept at these things. I did, in fact, find a way to partially work around this bug (the bug is the missing toolbar buttons or, said otherwise, no control buttons visible on the screen).

I discovered after lots of experimentation that I could get the little "Back" button to appear in the lower left corner. The way to do that was to hit the "?" and then immediately hit the Back button. Doing that returned me to the playing screen where I could continue moving tiles around. However, unlike before, there was now a Back button in the lower left corner. At this point, then, the only two buttons visible were the "?" in the upper right and the Back button in the lower left. There were no other buttons, such as the Settings button or the Solve button.

I uninstalled it on both devices - my iPad Air and iPhone 6S Plus. I wish the programmers well. It looked like a lot of fun to play if it were playable. Thanks for the thought.
