Overall a good and unique puzzle game. It adds different mechanics at a good pace to keep the game feeling fresh. My only complaint is that it's very unclear to me how I move around the world? I cant figure out how to back up and go do levels I may have skipped ... just in general the mechanic of puzzle selection is very confusing and awkward, but the puzzles themselves are fun.

Thank you very much for your review and valuable feedback! You can always go to the map (rectangular button in the upper left corner of the menu) and use the side arrows buttons to move between levels (Unfilled levels are not complete)

Great game! The game is very nice to look at and easy to control. It's like The Witness, but without twists and an open world. But there are two issues: 1) There are too many puzzles that contribute nothing. The ramping is so unbearably slow and the sections are mostly linear. In the best puzzle games, each puzzle adds to the player's understanding of the mechanic, but in this each puzzle is just an obstacle. 2) The end game is way too short. Only 10 puzzles that combine mechanics is a let down.

I'm so glad you like my game and thank you very much for your review and feedback! Definitely I try to keep the difficulty curve as smooth as possible because I don’t want to put too much tension on the player. I want to be sure the player gets the mechanic well and prepared for the next challenges. Last 10 levels are bonus and I plan to add more😉

Good puzzles, but after a while, you start getting long three part ads after every other puzzle, and the puzzles are quite short. This means more time watching ads then doing puzzles. I get it, ads are necessary in a free to play game, but too many and you drive players like me, who quite enjoy the game, away.

I'm glad you like puzzles and I try to have as few ads as possible. The ad content cannot be controlled by my, so the three-part ad is on the ad provider's side. Most episodes only have ~3 ads. All interstitial ads are skipable. In next update I'll try to display ads in even more balanced way. Also you can remove all ads by in-app purchase.
