OK, so one of you awesome students requested "Flash Hero" as a flash game on my site. Ive never played it before, but it looks cool, so I'll go ahead and add it.
Hold the keyboard like a guitar (a little difficult if you're using a laptop). Use the "NUMBER KEYS" as the frets, the "BACKSPACE" key is the strum bar. Use one hand to play the frets and the other to play the strum bar.
Press the backspace key and the corresponding fret to play the note.
Controls can be changed in the settings menu.
