Images are all replaced with the smug wizard?

[c]

When my friend talks to the princess, all of her dialogue seems to be replaced with an image of a smug wizard. No matter what option is chosen or how long the dialogue tree is, that's the only one that shows up.

When he tries to talk to the birds, the same thing happens. The smug wizard pops up in the corner instead of whatever is supposed to be there. This worked fine in browser however long ago, so we have no idea what's happening here. (This is probably the case for other parts of the game as well, but we haven't gotten very deep into it.)

Edit: This seems to be tied to save files for some reason? My friend could click on Load Game as soon as he installed it, which I noticed is grayed out for me. If he plays on the save created from hitting "Load Game," this issue is present no matter what. If he clicks on "New Game," though, he doesn't have this problem.

Actually talking to the wizard breaks the images in different ways. Some pictures will appear on top of each other at incorrect times, some will be stuck for a few dialogue bubbles before being replaced with another image, etc. It's very bizarre.
