Came out today for WiiWare, 1200 points.
First time playing the game myself, as the computer version only held one save file and my brothers were already playing it.
The game comes with updated graphics and music, though there are options to switch it back to the original ones. There are also more difficulty settings aside from the original (Easy, Original, Hard), and it comes with three separate save files.
Besides Story Mode, there is an option to play the game through as Curly, a time-attack mode, and one of those "beat all bosses" mode.
Fun game so far.
