Ports of Entry: Audiogenic Software

Having little familiarity with this British software house beyond reading its Wikipedia page, it's not clear to me if I should treat this as a continuation of Supersoft, or of Audiogenic Limited, or as its own thing entirely. The early games by those entities are of zero interest to me unless they can be considered ancestors to the games on this list.

Unknown lead platform:

 

Impact

First released for Amiga & Atari ST in 1987

Ported to Commodore 64 in March 1988

Ported to PC in April 1988

Ported to Amstrad CPC, BBC Micro, Electron, & ZX Spectrum in 1988

 

Helter Skelter

First released for Atari ST in 1989

Same-year port to PC

Released on Amiga in 1990

Ported to Amstrad CPC, BBC Micro, C64, Electron, & ZX Spectrum in 1990

 

Krusty's Super Fun House

First released for Genesis, NES, & SNES in 1992

Released for Amiga, Game Gear, & Sega Master System in 1993

Ported to Game Boy & PC  in 1993

Krusty's Super Fun House was originally designed as Rat Trap on the Amiga. What's not clear to me is if Rat Trap ever saw a commercial release. If it did, then the question is, was it reworked as Krusty's Super Fun House on Amiga first, or was that done on other platforms first and then ported back to Amiga?
