This is one of those silly games in which you just run and run jumping to avoid smashing your sweet face against a cactus, or any other random obstacle.
It works with python3 and the pygame module. random might be imported to (but it is provided with python3, not needed installation). I made an executable release for Windows with pyinstaller.
The game itself is under GNU General Public License 3.0 (or the newest if you make a derivative and you want to update it). The images are in the public domain: I think anyone can draw some lines and circles to make all the graphics. The text font can be found under public domain. However, I downloaded it under SIL Open Font License.
