My favorite game that has actual goals to reach. I never put money into the game. There is a mini game you can win gems to help with upgrades and ads if you want to get extra coins, but are not required to play. It's definitely challenging. I do dislike how some upgrades won't help you at all get three stars on some levels though. So, there is a requirement for certain upgrades to win a level with 3 stars...but you won't know until you keep upgrading everything.

#1. The Nightmare The Nightmare is a classic easy demon with slow pased gameplay, and is a very easy demon for beginners. #2. The Lightning Road The Lightning Road is an easy demon with colorful fun decoration, and is an easy demon. It features some tricky taps though! #3. Clubstep Clubstep is the first of 3 demons created by the developer RobTop. You can unlock it by collection 10 secret (star) coins! It features a little hard ship parts, but other than that it is quite easy!
