[comp.sys.amiga] DMaster-trap door at Rat level

PMXSG0%POPV03@dupont.com (08/15/90)

I am giving in too quickly, but after one evening of contemplating how to 
get into the door with the trapfloor behind it, I am ready to ask for a 
spoiler.  How do I get in?  I have tried things that obviously do not work (I 
am asking for a spoiler, right?) like a Mon Zo, Mon Fireball, chopping, 
running into the walls (ouch!), and Mon Lightning.  Obviously force is not 
the answer, what piece of finesse have I missed?
