Managed to get it running from the github repo. Looks like the requirements.txt file is missing. You can generate it by running

pip freeze >> requirements.txt

and then pushing that to github.

I like that you included lots of obstacles and character select, but I couldn't get past the first boulder.

Uh, you should publish a built/packaged version so that it's easier to play :/

To get this working on Python in Windows I also had to install the arcade module (which is taking a while, btw).

[twenty minutes later...]

Nope, still won't run. Running the script myself from idle it still says "No module found 'arcade.'

Is this a Mac Version? No win version?
