The game was drastically changed. It became an ad scam. After every 1-2 levels, I have to watch an ad. On many occasions they are 30 seconds long with sound. Imagine a situation where I am trying to relax with the puzzles during webinars/online meetings and other home office related events. Then, duddenly, an ad appears on the top of the video window with screaming profanities voices/music, ruining the promised stress relieve and mental development.
