Game will not load in Squeak 5.2 (alpha)

Found this via the Squeak home page. Loaded it into my image but when it runs it can't find the welcome_view.jpg file. Seems it's missing code to initialize the image and sound databases (which I found when I downloaded it via the potsdam page here: http://www.hpi.uni-potsdam.de/hirschfeld/projects/olpc/index.html). I downloaded the .pr file and loaded it into my image (after removing the package previously downloaded from this git repo).

Any chance that this repo can be updated to the latest working code? (since anyone else redirected here from the Squeak main page will run into the same problem I did)

Seems like such a great project - it would be nice to get it working under the latest Squeak.

Incidentally there is an error when running the code from the potsdam site as well. The game loads, music starts, allows you to select a level and then an error occurs. Below is the bug report from the Squeak debugger:
