We were on holiday this weekend, sorry for the delay in responses.
We always appreciate a mention of the tool to help spread the word if you want to help support us. We don't mind people customising the logo to the style of their game either. However I would prefer the original logo to be used without modification if possible, because it helps create a consistent brand image. In other words, it would be best to use the original unless you specifically want to fit the style of something else.
