Mr Freeze is a platform game that involves all of the usual platform elements – flying foes, gaps and obstacles to jump over or avoid.
There is also the threat of being zapped by a laser and frozen (!) if you spend too long on the ladders between that connect the shelves on each screen.
De-icing a compartment (screen) involves reaching the top of the screen alive and touching the large button handily labelled 'DE ICE'!
The flame thrower shoots a bolt of fire that will vanquish any flying food, but it's of no use at all against the ice cubes or the lasers!
