I hate to be mean, and I really don't want to start an argument, but "your" fret sprites are only a simple recolor of the sprites that took me over an hour and half to draw. You could have at least said that you edited my work or something instead of saying that the sprites were yours.

Can sprites be 64x64? If that is the case, can't we just use the existing sprites and just put a 64x64 invisible border around them? If not, I will be happy to resize my existing sprites. Also, will my guitar sprite make it into the game? I really hope so, because it took a lot of work.
Just to let you know, I will be emailing you all of my current sprites soon.
Also, I thought of a way for strumming to work. When you touch the screen a circle like this could appear at that location.

Then the stylus could move past the green line and that could register as a strum. Until you remove the stylus the object could remain in its current position, allowing the player to move over the green line numerous times with each pass over the line counting as a strum. Once the stylus is removed the object could be destroyed so that it could be created in another position. I chose a circle, because it would allow players to strum in any direction they want to. I'm not sure if you guys have strumming down yet or not, but this is just how I thought it could work if you were having trouble.
