99. Bumpy - Loriciels, 1989
As far as I can tell, this cute little game never got an official release in the UK. I discovered it thanks to a Your Sinclair cover tape, and it's my favourite of that weird bouncing ball sub genre that we enjoyed back in the late Eighties.
Each screen is a devious puzzle, and Bumpy requires considerable thought and planning to play.
It's a bit of a hidden gem, but one well worth digging up.
