User Reviews

The game’s puzzle concept and daily challenges are praised, but players are overwhelmed by long, frequent ads and a timer-driven design. Many call for a fair ad-free option and criticize monetization. Bugs and progression issues also appear. Overall, the core idea has potential, but the ad strategy, timer pressure, and occasional glitches are driving players away.

Pros

The core puzzle concept is fun and challenging.
Daily challenge puzzles add replay value and variety.
The game shows promise and potential with engaging design.

Cons

Ads are pervasive and long; often multiple in a row and disrupt gameplay.
Timed gameplay is stressful and not relaxing; many want an optional or longer grace periods.
Monetization feels unfavorable; ad-free options are tied to subscriptions or costly purchases.
Glitches/bugs such as freezing and daily challenge not registering affect play.
Progression can be hard or underwhelming, with some levels requiring tools to pass and unclear progression.

I couldn't get past level 32 due to the amount of ads. Just this one level continuously glitched out due to the ads. I could only play the easy part and when it switched to the "hard" part of the level the ads did not stop. I watched 4 ads and it still would not let me actually play the level.

The ads start out feeling reasonable but as you progress in the game they keep getting longer. Then they start showing 2 very long ads in a row. Once I was past level 60, there'd be 4 or more consecutive ads, with each ad lasting several minutes. I'm deleting the game after only two days. You'll be more successful if you rethink your business model.
