My newest projekt is a new app based on Tetris, but it’s not restricted to only turn 90 degrees at a time. Instead you have 360 degrees of free rotation, and all the pieces are affected by gravity.

The game is still in a very early state and only have the basics functionality implemented. You can try an early version of it at: There is no android version of it yet, but that’s to come.

The controls are atm:
Left and Right Arrow to move.
Z and X to Rotate.
Space to pause.
