Hey, I found a way to play the currently broken Steinway and Kanye levels:
0. Download the demo if you haven't already
1. Copy the link to the level you want to play and paste it into the address bar
2. In the url, replace "index.html" with "RhythmDoctor.swf"
3. Save the page (in Firefox, click the menu button and then "save page")
4. Put the swf file in the same folder as the demo ("RhythmDoctorOffline\bin" on my pc)
5. Drag it onto Flash Projector.exe
