A phenomenal set of tools for making Mario levels which, it turns out, are what you want. The basic handling of Mario is perfect, and exactly what you need for this sort of game. Serves as a great baseline of good feeling gameplay on which to build. There's a lot of versatility in the toolset too. While there are some discoverability issues, making levels feels so natural on the Wii U gamepad which makes it easy to put in the work. I made tons of levels, it's my favorite creative outlet. <3
