Ok the speed and the 'slidy' controls were bothering me so I've fixed them. Updated version attached.
I've also changed the name to 'Shifty Lifty' - just to differentiate a bit from the original.
I did try adding some music but it was major grief so I will try again later.
NTSC version attached, I can make a PAL60 version if anyone wants one?
No idea if this works on actual hardware - I would be very interested if anyone has a melody cart and wants to try it?
Not sure if I should continue this and make it a DPC+ game with multiple lifts or whether to just move back on to my other projects given that elevators amiss is already available. We'll see
