A few of my favourites:
Disposable Hero (ECS)

You have to click on the level links below to see the screenshots. Too bad they haven't got any animations there, as those were really what made the game stand out)
Super Stardust (AGA)

Ruff 'n' Tumble (ECS)
http://hol.abime.net/?id=1292 (one screenshot)
http://www.retrogaming.it/amiga/ruffntumble.htm (several poor screenshots - lousy colours)
Again, it was the animations that really made me drool. Superb stuff.
