Ren'Py 4.5 "Inked Finger" was released on February 5, 2005. It comes with a demo game intended to show off some of the features of the engine. The demo game was updated in version 4.5.
This version has a major memory leak bug, and shouldn't be used for releases.
There's a bug in the demo script that causes it to crash when trying to stop the movie. This bug is in the demo script, and not in Ren'Py proper. We apologize for the inconvenience.
The 4.5 demo can demonstrate MPEG-1 movie support, but no movie ships with it to minimize download size. To enable playing the movie as part of the demo, you need to download this Eisenhower Campaign Commerical (10.4 MB), and place it in the game directory of an unpacked demo, keeping the filename as "Eisenhow1952.mpg". To view the movie, choose "What's new in Ren'Py?" in the game." That file was found on this page of the Internet Archive.
