The author of this game is a guitar player and he likes [Guitar Hero] series very much.
"A guitar music rhythm game for Steam ? Sounds not bad !"
Then the author started to learn C# , game engines , finally the game is made.
KeyBoard Guitar Master is a guitar music rhythm game includes 14 original old school rock songs.
Only using Up Down Left Right arrow keys to strike notes, even people whom do not good at rhythm games still can enjoy this one.
You don’t need a guitar controller , there will be much more fun if you try to hold the keyboard as holding a real guitar when you’re playing.
