Meh.
I felt this game was pretty mediocre. The music was great, but the controls were stiff and the graphics weren't particularly fancy. Normally that wouldn't be too bad, but not that many people charge twenty freaking dollars for a flash game (not to mention a flash games based on an old Nintendo game. You expect me to pay $20 for something that isn't even original. I can download REAL Nintendo games on the Wii for a fraction of what you're charging).
NewGrounds is not a store. If you are going to make games, that's fine, but don't expect us to pay $20 for some unoriginal game that's merely decent. If you want to make money with your flash, either spend more time on them, or put ads in them like any decent flash animator. $20 for this game is just ridiculous.
