In my opinion, you should be able to hold lower keys while pressing higher ones for single notes. For example, if the riff goes R Y R, you should be able to do R RY R. I don't like to make this kind of comment, but Guitar Hero and Rock Band do this, and it only makes sense. Otherwise, good game!
@Das654 In the dark room, when the level title is scrambling, it actually changes to 'poeticend'. Look like the developer of the game beat you to that one :P
I think I got a bug or something. Somehow I got an insanely high score, which I didn't earn. @Admin: If needed, feel free to remove my badge and that score.
