Koopa Troopa Massacre

This is a survival challenge where you must survive the koopas and kill as many as you can! There's prizes at the end depending on how many points you get.

I played this earlier. It is a good tribute to Mario. The inclusion of the Mario tune was great.

Thanks Aven. This is now F4F, so I hope you guys could give me feedback.

Based on your youtube video, I'm guessing this level is better if you know how it's wired. I just died a lot because I couldn't figure out how to kill dudes. Jumping on their heads didn't seem to work, so I stopped doing that. The flower didn't seem to do anything. I wasn't in a sackbot, so I knew I didn't have any "superpowers." I wasn't going to stand there and try slapping dudes, so I hopped in the shoe and stomped in one spot, somehow unable to move it. Is it D-pad only and I just missed that somehow? I couldn't seem to do anything but get mobbed trying to get to the fiery helmet and fail to understand exactly how to defeat enemies.
