This is a game that I've been playing for a while now. I had a private beta but just this week it was released to the public. It's awesome.
The game engine is fairly simple, but the design mode allows you to actually build your own levels, using blocks, floors, hazards, moving platforms, powerups, etc.
On top of that, it has an online multiplayer mode (competitive and co-op) and, naturally, it's free.

I haven't made any of my own levels yet, but I'm hoping to get the time to make a couple in the next few weeks. My new account name is Faust. if you want to befriend me.
