Smashboards

It's very interesting!
So with the way it's designed, I can't tell if it's a Large stage or a medium stage, but it looks good!
The pipe on the left though, it shoots you through the air to the other side?
I suppose that's the only way it could work though, seeing as how the original stage had that pip on a midair platform.

And I suppose having the trap on the right instead of the left would work best for what it is.

Other Questions: Have you tested it yet?
Does the trap actually work?

All in all though, from what I can tell, it looks very well done!
Nice job!
