I have the game. Works like a charm and I didn't have to do any new updates (though I had updated pretty recently for Kirby). It's a good game. Controls are well... decent at best. The jumping is fine. Painting where you aim... not so much. Camera is also decent. Fine when it doesn't get in the way, but... when it does get in the way, it's pretty horrible.
And here's a tip... if you want to fully complete the game... then be sure to not skip anything. Do everything you can do in the area, before moving on. There also seems to be a good & bad deeds mechanic in the game. There's many means to get the job done, and how you do it affects some things people tell you in the game, some cutscenes and a few other things. Don't know how this would affect stuff end-game.
Also doesn't seem to be too short. I'm 6 hours in, just past the 3rd boss, and well... dunno when it ends. I reckon I have at least 2-4 more hours left though. Must admit I do skip something if I don't feel like it and randomly do good & bad stuff. The bad way is practically always the easy way.
Prolly the best Disney character game to come out in a while though.
My only gripe so far is that the sensitivity for the spin jump could be better. It feels like I gotta shake it pretty hard to get Mickey to spin. Would be nice if a cheat was made to map that control to a button(kind of like what was done for Okami). Besides that though, it's as good as I thought it would be.
From what I read from the Junction Point studios just last week, on average it was taking gamers about 15 hours to beat the first time. If you want to collect everything it can take near 25 hours. And in order to complete the game and see all endings and different scenarios, the suggestion is to play the game through at least 3 times making different choices than you did before. Sounds like a fun task to me
