Narwhal of Thunder is a game in which you control a Narwhal trying to escape a rising tide of lava. You need to stack the blocks of ice by jumping on them and stay away from the lava for as long as possible; if you become completely submerged in lava then you are dead!
There is only one control in Narwhal of Thunder, the spacebar. Press it to jump into the air. If you land on a block, that block is stacked and you continue going up. If not, you do not earn the points and the block can hit you. A block hitting you will take away 25 of your points.
