Now that I've finally got this old classic going (thanks to Brant!), I'm stuck exactly where I left off. A quick search turned up no walkthroughs or guides (no surprise!). So, I'm hoping you can help again.
I'm stuck at Level 24. This is reaaaally frustrating. There's a door, and for the life of me, I can't find another key. Any thoughts on where I can find another key? I swear, I checked every non-exploding payphone.
