It's certainly harder.
The game is not solved so there is no proof either way.
I recommend reading https://en.wikipedia.org/wiki/Bagh-chal. It introduces the game better than our "rules", I think, though as far as I can see it comes to the same.
In the "external links" section there's a link to a research paper, very long and boring. It explains why the game is so hard to solve. Here's the link: https://web.archive.org/web/20120313050451/http://www.yewjin.com/storage/papers/Computing_Tigers_And_Goats.pdf . Have fun reading.
