Well, all you do is go around and eat the little apples that appear at random. There's an enemy character which comes and goes again and again and eats the apples as well. You eat the apple you get one point, but if the enemy eats the apply, you lose one point. Plus, it gets difficult as the player keeps scoring (upto a certain limit, of course).
Its on Windows only right now, because I was lazy and didn't build it for Linux or Mac OSX, but the link given below is the Github repo, so if anyone wants to, they can just build it on their Linux or Mac OSX machine

EDIT:The game now has builds for Windows 32 and 64 bits and Mac OSX (thanks to Eamonn). Will be building it for Linux soon.
If anyone gets any cool ideas to improve this very simple game, I encourage you clone the repo, implement it and show us here

Critique, comments, praise, anything is welcome. Sorry for the long post.
