/*
Work For Chukka
Do scoring -- can be done on the basis of km traveled ie pixels here.. or no of icebergs passed by the ship.. former is easier
Make collision proper.. if you can come up with a triangle mechanism to check for iceberg collision
Add boundary collision.. make set interval function in ship ant call interval every 100 miliseconds
also write start screen . and game over screen.
Work for Rash
add lines to canvas making wawes
like /\
//\\
///\\\
add one line it will aouto matically replicate
learn on phone inputs and phone porting
