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.

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😉

Nice strategy puzzle game. Logic prevails, but sometimes I got lucky stumbling into a solution. I thought the puzzles were unique, and once I solved them all, I was hungry for more. It was a little bit buggy when launching... just hit the screen, and it will load. Manipulating between puzzles and levels sometimes required tapping a small navigation screen at the top...not obvious at first.
