Awesome, I knew there was a way to fling up there.

You got to see my beautiful hat, and yet you still want cake? People can be so demanding.... ;P

All in all, a pretty good map. Had a problem jumping over the junk (acid pool) at first, but eventually got over it.

How are you supposed to do the big room with the three pillars and the grate where you can shoot a portal to the other room ?

I used portal tunneling to get a portal high up there, but I don't think that's the proper way ?

Sometimes I wish I had never discovered tunneling, it makes some things way too easy.

iirc portal tunneling through a floor portal is the intended way.
It is also possible to complete it without tunneling, if you don't like that trick
