First project from new, young android developer topic

Can you please check out my first android project(game) for kids. It s animals memory game with cute sounds and nice graphics. Here is the title of the game, it s on the google play - Animals memory kids game - roqaj - developer. Please download it, rate it, comment it and share it. I would appreciate to hear some suggestions from more experienced developers(also for sounds, graphic etc.). I m aware that there is some bugs in the game, and i m currently solving them. Thanks
