The Atari ST/Amiga/DOS/Classic Macs had some great titles that everyone knows about - your Turricans, the Monkey Island games (or anything LucasArts back then), and Sensible Soccer if you lived overseas...

But what slid under the radar in these days? Have you dug something up that not many know about?

I'd like to offer...

Harlequin

Atari ST or Amiga offering... crazy non-linear platformer with 23 levels, a surreal exterior, excellent music and just the right level of challenge. Until you get used to it, there's a lot of WTF's per hour but even then - just crazy good times.
