Lots of bad things
The game is enjoyable and has a nice concept, but there are some things that ruin the gameplay. First, the controls. They could be better but are not bad. They are a bit slippery but mediocre. Next, I think it was dumb that you had to pay for the adventure mode. It is an ADVENTURE MODE. WHY DO YOU HAVE TO USE THE IN GAME MONEY TO PAY FOR IT?!?! Lastly, the level design, my worst complaint about it. The second level in adventure mode, it is so RIDICULOUSLY HARD to get the last collectable. It made me rage and delete the app that I just got 5 minutes ago.
