I'll have this article be quite a bit more in depth than the one of the main blog because people on Tumblr shy away from lots of text.
In this mode (currently dubbed "Scrolling") the player can only move left and right. Items fly at the player from ahead at a fast pace (kind of like guitar hero?). Currently conceiving a fun theme for this mode, and also working to incorporate more items into the game (more things for the player to think about). Planning cheat codes; because why not!?
Any suggested modes people might like to see?
