Pros:

A near perfect replica of Peach's castle and Bob-Omb Battlefield

Cons:

Needs more levels.

A Tank should have been at the top of the mountain

Conclusion:

Definitely worth downloading and playing through a few times., especially if you're a fan of Super Mario 64 Just don't expect a masterpiece. Hopefully, more maps will be added to this campaign like Whomp's Fortress or Cool, Cool Mountain.
