1990 Ocean Software (UK)
by David O'Connor and John Cumming
I only discovered 'Rainbow Islands' in the last few years. If I had played it as a kid It would certainly be on top of my favorite games.
It's simply one of the best games created for the Spectrum. And possibly the best conversion yet.
Incredible work by the Graftgold folks. Beautifully designed, full of colour, and highly playable.
