If it’s anything like the B&W Jam (also by Lone Rabbit), no.
However, that’s doesn’t speak to how a person might feel about a game that does or does not use the theme.
When rating games, it’s possible to filter by whether or not someone used the theme or not.
Personally, it’s an interesting restriction that I try to abide by and is fun to see how others approach it but doesn’t affect how I rate the game.
