Maze game
Way back in the days of yore, or last year as it's known, I was still quite fresh into the wonderful world of programming. However as I'd just joined college I prided myself on being the best programmer in my Computer Science class.
Then one day the whole class was in awe as some dude across the room showed off his 'Maze game'.
However his game was, quite frankly, rubbish. It was really rubbish code, and only had one easy to beat level. So I thought I'd take it up a notch.
The result was a multi-level maze game with times, custom maps, a map maker...all sorts. Suffice to say I won that war and his game was never seen again.
