Good idea, poor implementation.
The app is great in itself, but two things in it annoy me. The time limits and the amount of ads. It would be fine if one of these things was removed or reduced. You could even consider putting an option that let’s players choose do they want to play with the time limits or without, or with easier or harder time limits etc. It would make the game much more relaxing if everyone could play it at their own pace and figure things out by themselves. Then you wouldn’t need to look at the hints all the time either because of the time that’s running out. Also, when the time limits exist, you have to redo the levels many times which makes more and more ads pop-up, weakening the expirience and making at least me feel tired and bored of the game, eventually leading me to quit it for the day. The ads would be completely okay, if my suggestion regarding the time limits was added. PLEASE LISTEN TO YOUR REVIEWERS AND STOP SAYING “we are working on it”. Either remove the time limits or the ads. One or the other.
