Scuba Dive on the Commodore 64 must rate as one of the worst conversions of all time.
The ZX Spectrum original is an enjoyable and playable classic.
This version is a joke… The first area is just a single screen (unlike the original, where the surface was explorable over a number of screens). The sea creatures are blocky and look ridiculous. The graphics overall are pathetic (especially the scrolling, which makes the side panel judder when exploring the undersea caves), and the gameplay is a pale imitation of the imperious Spectrum version.
Whoever made this version of Scuba Dive for Durrell Software did a terrible job, quite frankly. It should have been much, much better.
