In the Loderunner-engine is a mistake that makes Loderunner fly. To 
fly start playing the first level of the file I attached. As soon as 
you run over a monk you start running and running (you can't stop), 
even if there is no floor anymore. After you ran out of the screen you 
can simply step back into it.

When you fly you don't run through nothing, you run trough hidden 
ladders.

For any questions you can email to konstantin@earthling.net .
If this address isn't working (and only then) you can also use 
ciman@geocities.com .
