Castle Infinity

Jump through floors:
--------------------
Hold [Ctrl] and jump to pass through floors that 
have rooms underneath them. 

There is a cheat for Castle Infinity. I don't know if 
it's a bug or not but if you hold control and jump, if 
the floor isn't directly over null space, (i.e. Going 
through the floor there will take you to beyond the 
beyond.) then you'll go right through the floor. 
An exception would be in your room looking at your points. 
If you do the trick here, you'll go down into the little 
tab and be able to jump off and into beyond the beyond.
