In my opinion, this was the best game. It was 'just' better than Ocean's. The key layout was all right with one key for dig and fill. The graphics are very good, being large, smooth and reasonably coloured, although there are a few attribute problems as monsters climb the ladders, but this was nothing to complain about. The sound is not very good probably the best on this comparison (all the games are poor and limited on the sound front). Sam Spade very playable and addictive with three types of monster and a fixed amount of oxygen available. I like this one most of all out of the selection.
Sllversoft have produced a fairly standard 'Panic' that has five platforms and a 'set' laddery layout (no random positioning). You take the place of a well-detailed and drawn man who moves smoothly and quickly. The same applies to the monsters, and the three different types (ech stronger and more intelligent than the previous) keep you very active, especially when trying to dig holes for the strongest ones which need to fail through three platforms. Good, fast digging action and colourful, noisy, unintelligent monsters with the added bonus of responsive and well laid out keys make this an enjoyable game to play.
