Game update for tropical death

For my tropical death game I decided to go simple and easy (as to keep up with my coding skills....) But I hope to make the game fun. 

My game so far:

You're on an island with an active volcano erupting! You must dodge the falling volcanic rocks gaining points for everyone that reaches the ground without hitting you. 

The game wont end until you die :P 

Once I have finished that basic game I wish to add more too it, such as falling bonus items, or maybe power ups. I will explore ideas like that after I have gotten the basic game. 

Tropical death scene. I have gotten the landscape to look topical and deadly :P The volcano smokes when the game is in 'play' mode. The green sphere in the front of the map is the 'player'. The player will move back and forth on the front of the island dodging the falling rocks.
