Suggested on the old forum and with great popularity, here's Tazmily so we can vote on it and hopefully get it into the game.

My idea for platforms is this:
It's a walk-off stage on the bottom, and you can walk upon the rooftops and flower areas as well. The red means you cannot fall through, and the blue means you can.
Occasionally, a Pigmask will jump on the top of the roof, and either jump down to the ground or stay. From there, they will walk around, shooting projectiles at people. You can attack them a few times to make them go away, though. (idea credited to AEM)
What do you think?
