You know you've had a good coding session when....

I do actually comment all my code as I type so I don't tend to lose track of what does what later on. I know that's not normal but it's good habit I've gotten into.

I've written down a few ideas at work just now to make the game look better tonight and add a few visual effects.

I general code in this order:

basic game design
main game loop code - the engine
extend game design
add new features
make it look better
add front and back end of game, menus, scoring, etc...
add some sound effects
add some music
make it look even better
write a small readme file for it
release it.
