the only part of that level that is really tricky is that you have to set a bomb to explode, which in turn causes a fire, which in turn makes you have to turn off the air, which in turn kills the HEEPS, which allows you into the room with all the HEEPS, so you can continue.
I did a fairly complete walkthru for this game a looong time ago, and Aaron posted it up on his site (thanks), or you can check it out on my lame PC-FX walkthru site
