Theme selector

This game is pretty solid except most of the puzzles seem easy with just a few hard ones thrown in here and there. Also, I wish you could select your color scheme instead of just having a set scheme that changes every so often.

Inappropriate ads for age rating!

Game is rated for 4+, and my daughter (6) plays the game. She is being shown ads for Las Vegas slots, with graphic imagery (naked women with nipple rings and obnoxious music) and other gambling games which are clearly not age appropriate. Ads are shown about every 2 or 3 puzzles and she has solved over 200 of them. So she has seen so many ads and these inappropriate ads start showing up. I have collected screenshots to give to Apple also. All parental locks have been in place on the iPad since being set up, so there is no excuse for these ads besides the game developer putting money before the interests of the age appropriate audience.

Great game, I have a suggestion

Hello! This is a great game and it’s really relaxing, but to make it a bit more interesting, maybe add like holiday themed challenges or color schemes, or maybe the ability to change the circles you draw with to other shapes or circles? Just a suggestion, you don’t have to. Other than that, great game!
