Knee deep in zdoom help

I was playing KDIZD and i cant seem to get past the intermisson, ive tried every key. Can someone help?

p.s Yes i am such a noob...

Have u tried looking at the low left side of the screen where it says either "view stats for player" or "view smt else which I dont remember know" and "continue forward"? you can change those with up/down arrow keys. Choose "continue forward" and push your fire key. that should do the trick.

And make sure you don't have noclip on when you enter the intermission map.
