About The Lost Adventures of Kroz
The Lost Adventures gathers new levels in the same text-mode style as the rest of the series, with every object the earlier games introduced, from lava and quakes to invisible walls. The hint program in the folder, KROZHINT, helps with the trickiest screens. It is the place to go after finishing the shorter episodes.
