Great Game! Fun to play, maxed out level is fun and simple. Require patience though. Easy to level up and good game! However there are little flaws but nethertheless its good. 4.5/5
Heres whats the 'Mystery Upgrade' does, once you hit the ground you will transform into something and will keep bounceing until you actally stop. Basically if you hit the ground you can proberly get an extra 300m+ because of that. Thumbs up for others to see and help them
