I just came across this…
I barely remember working on this, but I do recognise the scream. It’s not mine, as on the 1985 versions, it’s unmistakably my brother’s!
The aspect ratio of the screen also offers up a much more overhead view than the first versions. It’s also a lot faster than the originals because the 6502 variant in the Supervision was clocked at around 4MHz, practically RISC like.
Below is a screenshot I found on some site. I’ve removed their attribution, because the game is my copyright, not theirs. I quite like the more overhead look. Not sure I’d use it again though.
