Never used one of the cube buttons nor the reversed funnel...
I'll take another crack at it later.
Actually both of your solutions weren't intended - I will fix it right away 
[UPDATE]
Now I hope it's fixed (I'm not a bunny jumper, so for me it's hard to say).

Might need some more fixing.
PS. Sickle. I hate that song.
Thanks again!

Seconded.
EDIT: Sorry, thought I'd already posted about this map - I played the original version and did exactly the same as quatrus, then pretty much what sicklebrick did on the newer version. Looking forward to playing the finished thing, once all the unintendeds are weeded out.
Aesthetically I really like the look, though I'm not a fan of the repetitive water texture.

Well it does look pretty damn sweet.
This time I went for the intended solution and I think I have it:
It feels pretty legit.
Also as you can see the last cube jump is still possible. You might need to make that rail little bit higher.
4:23 am. Need sleep.
@quatrus:
Thanks for your feedback. I fixed problem with fizzlers and cubes passing through grid. I don't know however what do you mean by trapping inside funnel - player can always get out (and yes - killing himself in the process - but it can be predicted before jumping). Did you had the softlock?
