This game is spectacular. It feels like a true successor to the OG puzzle flash games like Bloxorz in a really cool way. It starts with simple puzzle concepts that mix together to create really engaging puzzles. And the intricacy of the levels scales up really well! I am both challenged and delighted by this game. The UI is super sleek, and my only suggestion is to have a text explanation of each button when you hold down on the option. At the very beginning I didn't know what the buttons did.

Edit: Sorry to hear it's been hard to navigate ad providers. The first time I opened the app, I never saw the menu pop up, just a flashing network icon. Now I see tapping the background shows purchase and dark mode. 🙌 Love the design but not the ad provider. The game has beautiful minimalist design with puzzles crafted to teach you to play without words.

Thank you for your feedback. I've tried a lot of ad mediations but mostly you see the ads from biggest providers on market plus they constantly change skip button design but I'll keep looking for a better expirience. Tip: Often skip button became active after several seconds. Edit: Thank you so much for updating your review!

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😉
