UPDATED SNAKE GAME
Description
This game provides all of the challenge expected from an "impossible" game while also making it's code very simple.what's New
Update 1.01Bug fixes and tweaks.
FLAW'S AND RECTIFICATION
There are 2 major Flaws in before game:-
1] speed of snake does not increases as score increases.
2] Even though Snake's Head touches it's Tail, game is allowing us to play further instead of showing GAME OVER CARD.
In this Update I fixed those 2 Flaws:-
=>First one is fixed by decreasing the TIME DELAY as Score increases.
=>Second is resolved by logical analysis that is if first circle touches any other circle then it comes out of loop.
.............HAPPY CODING,
VISWADEEP.
