I do not see how this would break any rules, we are free to use free assets - I don't see how that should be frowned upon at all. I do not make assets either, but I usually work with people who do - in any case: for me and NinjaBurger the process is the same. We get assets from somewhere or someone and put it together. I don't think anyone did anything wrong here. Very good job Ninja, making games for such a short time as a couple of weeks is only to be admired and I hope you'll be making many more! :) I have not been able to test this game yet, because I'm one of those freaks who primary use Mac, but I will set the high-score of high-scores later and get back to you! :D
