I can only guess but I think it is quite obvious
- the game took over 11 MB (8× 1,44" floppy disks)
- require hard drive
- require 386/16 Mhz
- released January 1993
A1200 was released only 3 months before so the market was very small at the the time of release. No HD floppy, no hard drive, way too slow. Nobody would bother...
