Here is a complete christmas game I made, including the source code, as a christmas present for everybody at TGC!
The download contains the exe, and all you need to compile it yourself.
Use arrowkeys to move, and space to drop a present. Dropping a present costs 500 points, so you must have at least 500 before can drop one. You have to try to get dropped christmas presents to land in a chimney. You will get 1000 points for every present landed in a chimney.
You must not crash into the ground, or the chimneys or snowmen. Also, you must not hit a plane or helicopter. You can use left and right to speed up/slow down, and up and down to dodge stuff.
I made it pretty easy, as it's a christmas game, but it's still good fun
