Falling Up 004

Falling Up its another tetris clone. No, Im not trying to make any money off of it or claim it as particularly unique. It is fun. Try it. Its evil. Im told that frequently.
People have even praised it. I wrote it as a precursor to other games, a way to learn new technologies (GLUT, OpenGL, OpenAL, NSIS, ...), and to brush up on old ones (c, for that matter).
The source code is essentially free to do with as you please, if you like. If you "steal" most of it, Id prefer you give credit back to here, but really... whatever. I learned from lots of places and anything I can do to pay that back is cool.
The game is... tetris. You have the same old blocks, and they fall down. You use left and right to move blocks left and right, up to rotate, down to move down a line, and spacebar to drop.
Theres a next item (optional), sound (optional), and... stuff like that. Please, just download it and play it already! Geeze! Youd think I was just rambling...
Enhancements:
- The score file was adding 1 to the "level" the score was attained at every time a new high score was made, give or take; that is fixed.
- I added a background image (doesnt work with trails, may slow down on slower systems), and made F4 quit out of playing the game.
