The Linux version (maybe others too) has a major bug that makes the game crash in the first few moments. The paths to the character images in script.rpy are wrong. The have have ".png." instead of just ".png" (ie. extra dots).
Thank you for letting me know, I'll see what I can fix
Once I figured out what was going on it was just a search and replace on the one file.If you're familiar with vim: %s/png\./png/
