Great and different endless runner

You are a scientist “running” in a particle accelerator and discovering particles and principles by accomplishing the levels. What makes this game great is the level design. Each level has new challenges. Minimalistic but thoughtful changes in the design make each level a new experience. Which is what I find sets it apart from other runners. Enjoy this one.

This game is absolutely fantastic. Tight and reliable controls, not a single lag issue, simple and addictive gameplay, no in-app purchases, stylised sound and visuals, and online leaderboards, this is perfect for high score chasers. There's only one issue with the game. It's too short. With only 6 levels in the game (admittedly the last 2 are ridiculously difficult- took well over 500 tries to beat them both), it can't be given a perfect score. But for an adaption of an online flash game, this is superb, well worth the money. With an update that adds more levels and gameplay styles, this would be one of the best apps on the App Store.

Challenging but not impossible

Other reviewers are saying it is impossible to beat/ too hard. They should go play with peppa pig or something.
It is true that sometimes there is nowhere to jump, but this is mitigated by thinking 2 steps ahead, the game forces you to use your head as well as your reactions.
Awesome music, very addictive, not for babies that don't like a challenge.
