For me as a coder, I wonder what the appeal would be for a "somehow inbetween" version of Limbo.
First off, if I want to play Limbo, I can do that on around 3 or 4 different devices in this household.
The C64 version is impressive, because it's taking what the C64 has to offer, and pushes it to its limits.
If somebody took a stock Amiga, and made something comparable with the Blitter, Sprites and Coppermagic the Amiga has to offer, it would be fascinating for me.
Using a 030-config with the sole intention to use the faster CPU to bring more stuff unto the screen sounds boring to me.
Your mileage may vary, off course...
