I'm still struggling with Level 2 and I can't get through the gates - the ones with a half dome in middle and sharp edges on top. In level 1, I could shoot at the center and sometimes it would open. I could also fly "though" it if I press the jet pack while going up.

So far, in level 2 I just crash! Any helps? I'm getting verrrry frustrated!

Also I saw that using F12 and F2, F3 or F4 could restore health, jet fuel, etc. but these do not work for me. Nothing happens. Any clues why not?

I do enjoy this game though ... it's becoming an addiction. So help this addict get through Level 2 if you can. Thanks!
