In theory, this could be a good app. In practice, it is not given the reluctance of the developers to fix long-standing issues. I have an iPhone 6 and 1) the light beams game cannot be played at all since there are no mirrors to drag; 2) the worldly words game has problems as words are often cut and not displayed properly; 3) the reading blocks game is awful because objects are not aligned with the rows of the grid. I would appreciate it if these issues could be solved sooner rather than later!! Also, if they work on the app, they should listen to what most users have written in the reviews and take out the useless emotional section.
