Funny I never knew there was a cheatcode for castaways, is it that good old midway up up down down left right left one?
@Catfish, the game is quite possible without cheats, it's all a matter of knowing what to build where and how, indeed there are a number of winning stratogies that people have employed.
It's been quite some time sinse I played castaways myself, I need to give it another go actually.
Oh, and if your interested in different people's takes on stratogy in the game (including mine), see This topic
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
