------------------- ABOUT ----------------------
--
-- In the desert planet Hero will have to explore
-- the dunes below the surface and find the hidden
-- crates. It is told that one crate contains the
-- lost part.

-- Idea: game will be successfully end when the 2 lower crates are collected
-- it would be more defficult (and sadistic) if one should collect *all* the crates
