No Words.


This game is easily one of my favourites out of any game I have played on the app store, hands down. From the moment I first wiped out, I knew I would eventually unlock every particle. And that I did, up to the Anti Boson X. It had me coming back time and time again, every time I was bored or otherwise, slowly making progress toward that last particle. And oh, how it was satisfying to finally get it, For the love of all that exists, pick this up.

Needs iCloud Save!


Great game, so much fun and extremely challenging. Just needs cloud save so our progress isn't for nothing. If there are no more levels to be added in the future then an update to save our progress in the cloud is the least to add. That would be really helpful and make this perfect. Thanks!

Not worth it


While this game may seem cool at first, that's really all it has going for it. As you sink your teeth into the later levels, it relies on tactics to make the game more difficult that end up being very frustrating instead of fun. For example, one of the levels changes the texture of the platforms so you can barley differentiate one from the other, that being the main difficult part of the level.
