------------------- ABOUT ----------------------
--
-- In this cold planet hero seeks for a part of the
-- antigravity device. He has to capture Icy Pit who
-- knows where the device is hidden. Hero will be
-- able to use only the ice gun for this mission.

-- TODO
-- alter map so hero may climb to the higher place
-- maybe use rope challenge to go there
-- add checkpoints
-- fix the stats
-- Add first checkpoint save if icegun is taken
