Ok, I want to get this clear before people start commenting. This is a CUSTOM LEVEL made with the Project Arrhythmia level editor. Before talking about how similar this game is to JS&B, keep in mind that JS&B and Project Arrhythmia are two different games that just coincidentally have similar gameplay. Project Arrhythmia is its own game that started development at least 6 years ago, neither PA or JS&B were made with any knowledge of each other so it is just a coincidence of multiple people having similar ideas.
