I have been playing this game the past few days now and I agree with whats being said here. That being said I think its an excellent game. I highly recommend it to any one with an iPad.
The guys from Tested talk about and review the new Adobe Ink and Slide. Personally I have always considered getting a stylus for my iPad but never really went for it. Came close many times but never went through with it. This looks pretty cool but im still skeptical.
