You're right that a lot of these furry casual games do tend to just steal art and the like, but seeing as how here the characters are actually integrated into the UI and animated and whatnot, I don't think the art's stolen in this case.
This game kinda looks like at the very least a teensy bit of effort went into it, at least compared to some of the other random minigame collections with an unrelated gallery of stolen furry smut attached to it.
Anyways, thanks for the upload,
BaasB, you're the best.
