Thanks. I am finding myself wondering if making the input either or up and down Arrows fits withing the spirit of polish. Not sure if it's a fundimental change or a minor tweak...
I think it closes tonight at midnight. I decided to leave it as is. Part of it being that way was to do with the theme anyway. The boost is behind and thus the control points backwards. Subtle and not really that significant but that was my contribution to the theme, exploring all the bits I could with leaving behind.
