I just played through the whole game (PC version) and had a blast, it plays like the original so as long as that is what you are looking for; which is an updated version of the original game, then you shouldn't be disappointed.
It really felt like a lot of care and attention went into this, the animations on the characters are really well done, the remixed music sounds great and I really enjoyed some of the dialog the characters come out with. It was like a new episode of Duck Tales. Hearing these characters talk again for the first time in decades and with their original voices is just so awesome.
Heres a few pictures I took
The only thing I didn't like was the that controls didn't feel quite the same as the original. A few times when I was trying to attack with the Pogo move, it wouldn't work sometimes. I think this is down to me using a 360 controller though, the d-pad isn't quite as responsive as I'd like.
