The Atari ST conversion of Bubble Bobble is very similar to the Amiga version, except with slightly muted colours. It was programmed by the same guy who made the Amiga port (David Broadhurst), so no surprises there.
The Atari ST conversion is often forgotten/dismissed next to the Amiga version, but personally I prefer it to the Amiga port, if only slightly. The controls – in the version I played – were less twitchy, and I found myself dying less often due to control mishaps.
The 16-bit Atari ST and Amiga conversions were both handled by Software Creations and published by Firebird Software in May 1989. The graphics in the ST version were created by Andrew Threlfall, with music by Mike and Tim Follin.
