I tried the demo, it was okay. It has generally gotten average to low reviews and even fan reviews aren't good.
Judging from the demo, I wouldn't buy it (obviously, as I played it and didn't) but there are some people who enjoy it and thought it is worth it.
My suggestion is try the demo first and see.
