On the last day of GDC this week, I heard from developer Anthony LaMantia, who had a new game named Moon'd that he wanted to show me. We met up in the lobby of the Austin Convention Center, and I got to play around for a bit with his game, a platformer with a strange twist. Instead of playing as a cartoony character like Mario or Sonic, you play as a 3D block and use left and right buttons (along with a jump) to "roll" the block around some abstract stages.
It's a weird setup, but it works. The controls are a little flighty, but responsive, and the physics allow you to do some interesting things while moving around, like catching the edge of a block on a platform, or pushing a ball underneath you. LaMantia said that the plot involves saving the cow that jumped over the moon, but I didn't see any sign of the cow anywhere except the title screen. The stages involve getting your cube to the end of an area, or collecting a certain number of coins along the way.
