I'm sure this glitch is well documented, but it can prevent Diz getting burnt by lava going back across the wooden bridge in the mine. Stand half-on-half-off the lift before the bridge, go up, and Dizzy floats through the ceiling to the screen above.
In an otherwise very smooth and seemingly bug-free emulation (are there any more bugs?) the lift trick is a nice reminder of Dizzy's earlier, more rustic days on the Spectrum.
