What a fun game! Both me and my girlfriend really enjoyed the hour we had with it so far. I particularly like the art style, music and overal tone, which combined together with the arcade-like, quick paced gameplay result in a very involving and colorful experience that has depth as well.
The only thing we both had trouble with, is the controls though. I tried all options and while I think I prefer using the stick to control camera movement, for aiming I can't seem to get a hold of the speed with which the camera moves. Even on the lowest sensitivity setting, I have great trouble with long range weapons when trying to keep my reticule from flying all over the place in other words. This might be something I have to get more accustomed to, but so far my only remedy as not to suck completely was to use the roller (which is great fun as well).
That aside, I'll try to play some more tonight and I can't wait for the full game (+ amiibo) to get here on the 29th! Hopefully there will be a healthy community for the game - if so, it could be a nice alternative to Smash and Mario Kart when it comes to Nintendo multiplayer games.
