Cascade Beneath by ThatOtherPerson is a simple fall down clone. You just move from side to side and try to let the platforms push you off the top of the screen as they slide up.

Release notes:

Here are two more updated games of mine. Both have online scoreboards (don’t forget to go check your scores by hitting the network button in the bottom right corner of the home menu) and all the other coolness that my other recent releases have had. They are really ports of the PS3 ports of the original games. So they don’t use SDL anymore and look (and probably play) slightly differently from their previous Wii versions. Neither of them has music (as I remember it the Cascade Beneath music wasn’t very good anyways).
