(the initial thread is too old now)
I have improved a bit my first game, Space Zig zag, in which you have to drive your spaceship in an asteroid fiels as long as possible. There has been some code cleaning (including a few things in my game framework library browsable in this mercurial repository), but more importantly for the player, the game now count how much asteroids the player crashed into, and it keeps record of your best data as well as the cumulated data, attributing stars to each one (thus there are 12 stars to unlock).
I have posted some screen shots in my gallery.
