This is one of the most original takes on the theme I've seen! The only one to go with cheese craters, too. The gameplay is pretty interesting, had some challenge.
Criticisms:
Sometimes the new marbles got stuck in the opening hole and there was no way to get them out. An unpleasant way to end a playthrough.
The texts in the main menu buttons had an interesting font, but it was really hard to read. Maybe it would be easier if it wasn't transparent.
The other stuff (audio, more "faces") you mentioned in the description, so won't get into those.
