Fully played in co-op, which was also the reason why I even finished it. The game just didn't feel nice to play and that's mostly because of how the controls felt.

My thoughts:
(+ = (mostly) positive; - = (mostly) negative)
- Gameplay;
The controls were slow in all ways possible. Hitting an enemy never felt like it landed and the depth perception was off. All levels were unique enough, but mostly not really fun to play because of the reasons mentioned earlier. It's so important to have controls that feel nice to use. It can decide the whole experience for me.

+- Music;
It's alright I guess.

+- Graphics;
Charming but not as creative as it could have been. Paper Mario or yoshi woolly world for example use the environment in an unique way.

-- Story/Characters;
Zzzzzz....

Recommend?
No, plenty of other games that do the job way better. Super Mario 3D World for example.
