Oh my! I'm usually not easily fooled, but these puzzles are challenging. And there are very few ads. I like it the way it is right now! So I thought "I'ma buy this game; it's worth it!“ Figuring out how to do that, however, was quite a puzzle in itself. You need to be playing any puzzle, click a blank portion of the screen, and then select the middle icon at the top... Sneaky stuff!

Hi! I really enjoyed your game, the mechanics are very well introduced, neatly interact with each other and the execution is flawless. The game feels really simple through its design yet quite challenging! I enjoyed a lot all the levels. I wanted to thank you via an in-app purchase (the add free option, maybe?). However, it seems it can be bought only from a level, and it is not very clear how much it actually costs. I enjoyed these puzzles a lot, and I am eager to try more of it! Thanks again!

Fun puzzle game. Enjoyed it quite a bit. A few of the levels were a little annoying or frustrating, but otherwise it's engaging from start to finish with a good variety of difficulty and gimmicks. 4 stars mainly because I found the level select UI confusing. I figured it out eventually, but it's not intuitive. Strong recommendation from me if you enjoy logic puzzle games that aren't overly difficult.
