A minimal Tetr*s clone created in a couple hours and a few hundred lines of code.

• Press “Start” button to start the game, “Stop” button to stop it. D’oh.
• Use the buttons to control tile movement left/right/down and tile rotation
• Tap the game view to rotate the tile
• Drag down on the game view to set tile straight down, same as the down button

• Game over detection and handling
• Better tile rotation so that it always works, even when tile is at screen edge
• It does not feel quite right (hard to describe)
• Improved graphics & UI
• A scoring system
• Animations
  • When moving/rotating a tile (Maybe not, though.)
  • When line is cleared (Explosions! No, really, a particle effect would be awesome. Something like in Letterpress.)
• and much more…
