It's inviting & exciting, great fun until you reach higher levels then it becomes disheartening & impossible to complete levels...I've found myself stuck on any given level an extremely long time despite playing daily ..& now I'm getting bored of it all..I'm currently on level 1954. Definitely NOT without making purchases. .. I've found TOON BLAST to be a much fairer and achievable game on higher levels without having to make purchases..
