Well I tried the Atari ST version and it's not as colorful as Amiga, and there's only sound fx, which aren't as good as the Amiga ones. Otherwise the game plays ok, although it takes a long time to load from floppy disk (Amiga is quicker here). Anyway the Amiga music and graphics really make this game shine so it's not worth playing this ST version unless it's 1991 and all you got is an Atari.
Another good platformer nobody heard of is Lollypop, for Amiga and DOS. The music here is again top-notch, but I couldn't try the DOS version because I can never get it working. But for Amiga version it's enough to use Kickstart 3.1 and set 2 MB chip ram, and no slow or fast ram. The animation is perfect, and there's lots of cool details. Also they have given the option to use various controllers, including keyboard (which is nice for me, because I usually prefer it).
