Can you make the screen blue in 50 levels?

Best Game Ever

I like how you guys don’t put to many ads. I’m usually not really obsessed with puzzle games, but yours are so gooood. The thing is that it’s rather calming then annoying or upsetting. If I do get annoyed it’s probably because the hints are not clear enough. I like the balance of this game, it’s not to hard and it’s not to easy. I also like how you guys respond to your reviews, really shows that you really care. I’m so glad I found this game. This needs more download. I’m a little sad this is the last of your puzzle game, but I’ll be waiting for more!😄

Some levels need more distinct shades

Some levels like 12, and 37, and 41 rely on moving fish or blocks over white spaces. In these levels, the objects are indistinguishable from the obstacles, or the shade of the backdrop. I'm not sure if it is an intentional design or if my display settings are somehow incompatible with the game's graphics, but a slight change in hue could be helpful. Otherwise it is impossible to tell what you're doing. You are just blindly swiping until your thumbs cramp. I love the other games (red, black, green, etc...) by this creator so I am giving this 4 stars in hopes that this will be corrected. The puzzles are somewhat unique and challenging albeit not as good as the other games it still provides a nice relaxing challenge.

every thing is cool ,
