DSiWare: Flip the Core
Here's a little gem I discovered that DSi/3DS owners should be keeping an eye out for. This goes out to all those that thought that DSiWare was dead, including me. Flip the Core is quite a unique shmup that allows you to flip the perspective of the game, similar to a Paper Mario or Fez style. The game is being developed by Engine Software and was described as labor of love at GDC.
