Ratings and Reviews
Your product is now trashed with adverts between resets. It's not even possible to get a focused mental workout now, with ridiculous ads popping up. Not mention the ad banner stuck at the bottom of the homepage. Honestly, you've ruined it. Please limit ads. At least remove them from resets. Or offer the older version before today's update.
It’s really impossible to play. Please, I’am ready to pay for playing without adverts
This was, at one point, an excellent mental exercise; however, the current version inserts an advertisement–one that you must interact with in order to surpass–between each attempt. This mode of usage is cumbersome and infuriating. Please limit adds or offer a 99¢ version that is free of ads.
