It’s got both content and issues.
There’s actually a lot of performance issues with this game. If you’re a fast player like I am, the game has a hard time keeping up with faster marking after a while. It gets so bad that it actually slows your phone down to halt, at which point you have to give it time to process to catch up and load whatever it’s loading. Using the app heats up the phone and occasionally the app crashes as well out of nowhere. Most progress is saved though, so while getting a crash is annoying, it doesn’t hinder the progress too much. On the positive side, the app has a lot of stages, so you’ll have enough to work with. Some pictures are a bit of a hit and miss but I haven’t seen anything too jarring in the themes. There’s an achievement catalogue for those who care for them, and I think you can make the adds go away via a small purchase, otherwise you’ll see a short add every time you finish a level. If you have the patience to work with the performance issues like I do, this is a 3/5, for the less impatient people it’s probably not an ideal download.
