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.

Every 3 levels there's a pop up ad that requires 3 clicks to exit and lasts at least 10 seconds. At this point it's an automatic 1 star no matter how I feel about the game, because I'm spending more time watching ads than playing. Edit: thanks for your response! I believe you can control how often the ads roll, so my review remains valid. Cheers!

All interstitials are skippable, but sometimes ad providers make it difficult to skip, and as a developer I have no control over that. You can always turn off all ads by making an in-app purchase or subscribing to Play Pass, it costs less than a cup of coffee☕️
