More Tetris

I thought I'd post some of what's on my current TODO list for the tetris project:

• Add a background:
  Should include a sky and some ground, but levels can be indicated by the following:
  • Trees
  • Bushes
  • Flowers
  • Hills
  • Clouds
  • Cliffs (towards later levels)
  • Waterfalls (usually off the sides of cliffs. May have some trouble animating them)
• Add an Options screen:
  I'm not yet sure what to put here, but something about background music, enabling sound effects, graphics detail, etc. would be a good idea.
• Add sound effects:
  A light thud for blocks landing gently, a slightly heavier thunk for blocks dropped from a higher height, some kind of explosion for when a row gets removed (or maybe a cool disappear sound, I'm not sure), etc.
• Add background music:
  A friend has offered to make me a Techno remix of the original Tetris background music, but you can be sure that if I include that, I'll provide an alternative option as well as the choice of turning it off...
• Add an in-game menu:
  To pause the game and let the user change settings without having to restart their game.
• Add levels of difficulty:
  Because one level isn't challenging enough.
• Add a highscore list:
  To record how well you've done. I'll probably use SQLite to keep things relatively simple.
• Tweak or rewrite the font engine:
  To add multiple brightness levels. Right now, fonts don't look that great and could use some extra zing.
• Write a shaders module:
  To allow me to use shaders on a variety of platforms and even on some lower-end systems, including low-end Intel graphics cards.

Current status is that things look and play fairly well, but certain aspects could be greatly improved, such as block textures (I'd like to use a bump map, but that requires I use a shader so far as I know, thus the need for a shaders module).
I also seem to have lost some of my enthusiasm for work on this project, partly due to finally fixing textures (now I don't have a big challenge staring me in the face, just a bunch of smaller ones).

I want something big and difficult! Not small and difficult!
(sounds weird, I know)
